ANTS
|
I have only seen a few ants. Does that mean I have a
problem? The number of Carpenter Ants you see is not a direct indication of the severity of the problem. At minimum you should have your home checked at least once a year.
AMTECH offers the Residential Five for your continued peace of mind or is on
call to safely eliminate your pest problems. |
Are what I’m seeing Ants or Termites? Termites have broad, thick waists, whereas ants have narrow, thin ones. Ants’ antennae are bent at right angles and are elbowed. Termites have slightly concave antennae. Ants have three distinct body parts. Termites have what appears to be two, the head and body. AMTECH's Fully Trained Professionals not only will help you answer this question, but will eliminate the pest for you, |
What signs indicate a possible ant or termite nest
within the home or structure? Possible signs of an infestation within the structure include: Seeing ants within the house during colder off season months. Frass (sawdust like material) usually containing ant body parts. (Carpenter ants chew wood and brush it out with their feet. In addition carpenter are carnivorous, thus the ant body parts.)
AMTECH technicians can do an onsite assessment for you; email us or call us for an appointment. |
.
ROACHES
|
Why are roaches so difficult to eliminate? German Roaches (the most common species found in buildings) are difficult to eliminate because they have a very high reproduction rate. They are also thigmotactic; that is, they prefer squeezing into small cracks and crevices where they spend 75% of their time. So when you see one roach, chances are there are many more that you cannot see. AMTECH technicians with an average of ten years experience can do an onsite assessment for you; email us or call us for an appointment. |
What non chemical means can I use to help control
roaches? Roaches need three basic things: FOOD, WATER AND SHELTER. By reducing or eliminating their supports you can greatly reduce the population. Good sanitation along with caulking cracks and crevices will also help. AMTECH's safe and environmentally friendly solution will solve your problem, quickly. |
If roaches are so difficult to eliminate, how can
AMTECH offer a One-Time service with a One Year Guarantee? We use a variety of products that while extremely low in toxicity are very effective in eliminating roaches, such as baits, insect growth regulators which prevent immature roaches from reproducing, and sorptive dusts that abrade their outer covering causing them to dehydrate and die.

Camponotus species Carpenter
ants range in size from one-quarter inch for a worker ant to up to
three-quarters inch for a queen. Their color varies depending on species,
from red to black or a combination. The two most common species are black. Carpenter
ants get their name because they excavate wood in order to build their nests.
They mainly attack wood that is or has been wet and damaged by mold. Even
though these ants first invade wet, decayed wood, they may soon begin
building paths through dry, undamaged wood. Their excavation results in
smooth tunnels inside the wood. They usually come into buildings through
cracks around doors, windows, ogr wires. They will also crawl along overhead
wires, shrubs, or tree limbs that touch the building far above the ground. Habitat |

Family Rhinotermitidae Subterranean termites live in underground colonies that can
contain up to 2 million members. They build distinctive "mud tubes"
to gain access to food sources and to protect themselves from open air.
Termite colonies are organized into castes depending on tasks -- workers, soldiers
and reproductives. The characteristics of a subterranean termite are
dependent on the termite's cast. Cream-colored Worker termites are 1/8 to
3/8's of an inch in length. Soldier termites are of a similar body length,
cream-colored bodies and brown heads, but are distinguished by their powerful
mandibles. Reproductive termites are approximately one inch long, they swarm
in the spring to start new colonies. Habitat |

Facts About Rodents and Rodent-borne Diseases
Rodents usually can spread diseases, including potentially lethal hantavirus and arena virus. House mice constantly give off hundreds of micro-droplets of urine as they travel around their territory every day. A large medical research study showed a protein in house mouse urine called mouse urinary protein (MUP), caused allergies in 18% of the inner city children studied.

rodents
Facts About Ticks and
Tick-borne Diseases
Ticks are more closely related to arachnids, such as spiders and scorpions, than to insects. Like a spider, a tick’s body is fused into a single region. Conversely, an insect’s head, thorax, and abdomen are separated. Several tick species in the U.S. (and similar ones in most countries) are known or potential vectors of tick-borne diseases that infect humans, pets and livestock, including: Lyme disease, Rocky Mountain spotted fever (RMSF), Human monocytic ehrlichiosis (HME), Human babesiosis, Human granulocytic ehrlichiosis (HGE)
There are two
families of ticks:
Lyme Disease (LD)
·
Caused by spirochete bacteria Borrelia burgdorfer.
·
Most common tick-borne disease in the U.S., mostly in Northeastern
states of Connecticut, Rhode Island, Massachusetts, New York, and New Jersey;
in the upper mid-western states of Wisconsin and Minnesota; and in the Western
states of California and Oregon.
·
Increasing number of diagnosed cases in the Southeastern and
Southern states.
·
Symptoms include a “bull’s eye” rash around the bite, appearing
within three days to three weeks; flu-like symptoms such as fever, chills,
headache, and extreme fatigue; arthritis of major joints which “comes and
goes;” and severe nerve disorders such as Belle’s Palsy (in which one-half of a
person’s face is paralyzed) in later stages.
·
Anyone who has been in an area where ticks are found and develops
any of the symptoms mentioned above, especially from May through early Fall,
should see a physician for evaluation immediately.
Rocky Mountain Spotted Fever (RMSF)
·
Caused by a rickettsial organism, Rickettsia rickettsii.
·
Found in the Southeast and South-central U.S., including Oklahoma,
North Carolina, South Carolina, Virginia, West Virginia, Georgia and Tennessee.
·
Symptoms include sudden high fever, malaise, chills, muscle aches,
bloodshot eyes, and headaches, appearing three to 14 days after infection;
nervous symptoms, such as sleeplessness, restlessness, and delirium.
·
In at least 50% of patients, a characteristic spotty red rash
occurs on the soles of the feet and palms of the hands within two to three days
after the rapid onset of a high fever.
·
Thirteen to 25 percent fatality rate for untreated human RMSF
cases.
Human Ehrlichioses
·
Caused by a rickettsial organism, Ehrlichia chaffeensis.
·
Reported mainly in Southern states.
·
Symptoms include fever, chills, headache, aches and pains in the
joints and muscles, loss of appetite, eye pain, nausea, and vomiting.
Human granulocytic ehrlichiosis (HGE)
·
Caused by a new, unnamed rickettsial organism.
·
A relatively uncommon disease, but fatality rates are usually much
higher than for HME.
·
First isolated from a tick from Wisconsin in 1995, and has since
been reported from at least seven other states.
·
Symptoms include fever, chills, headache, aches and pains in
joints and muscles, loss of appetite, eye pain, nausea, and vomiting.
Babesiosis
·
Caused by Babesia microti, a pathogen of certain meadow mice,
transmitted mainly by the black-legged tick in the northeastern U.S.
·
A rare, but sometimes fatal, disease mainly infecting humans who
have had their spleen removed, are very old, or have weakened immune
systems.
·
Symptoms resemble a mild form of malaria, and medical difficulties
are almost always due to misdiagnosis or diagnosis very late in the course of
the disease.
Tick Paralysis
·
An acute paralysis of motor nerves of mammals, fatal unless the
tick is removed
Results from direct, long term contact with infected ticks (which generally attach themselves to the nape of the neck or behind the ear for several days or more).Rodents
Animals that may come indoors during winter include mice, rats, squirrels, and sometimes even raccoons and opossums. Rodents may come in through almost any opening – pet doors, holes in walls, missing vent screens, openings around pipes, dryer ducts vents, etc.
The roof may also be a handy highway into your home. Rats can climb plants or trees that are too close to the house. That’s where roof rats get their name.
An estimated that 21 million homes in the U.S. are invaded by rodents each year winter. In the U.S., rodents try to come inside from October through February.
Mice can squeeze through spaces as small as a nickel. Rats can squeeze through a space as small as a half dollar.
You know you have rodents when you can hear scampering or gnawing sounds late at night in the attic or behind walls. Telltale signs of rodents’ gnawing may be seen on packaged goods, cardboard boxes, and walls near pipes and vents. Inside, rodents can be very destructive. They chew through wallboards and can eat through cardboard boxes, wood, and plaster. Rodents gnaw on electrical wiring that could potentially cause an electrical fire. Rodent droppings may be found in undisturbed areas of the house such as pantries, attics, garages, under baseboards, and along walls.
Keeping
rodents out
Cockroaches
Cockroaches have been
around for more than 350 million years. Most species live in tropical or
subtropical areas and nearly all need warm, dark, moist places to hide during the
day. They nearly all will eat anything available, from sugar to rotting leaf
litter to feces. They are important in recycling dead and decaying matter
(especially dead plant matter) in their natural settings.
Cockroaches often are a health threat.
In general, the habits and high reproductive rate of pest cockroaches can lead
to large populations which spread disease organisms, contaminate and eat our
food, and cause allergies and even asthma.
Cockroaches have been reported to spread at least 33 kinds of bacteria, six
kinds of parasitic worms, and at least seven other kinds of human pathogens.
They can pick up germs on the spines of their legs and bodies as they crawl
through decaying matter or sewage and then carry these into food or onto food
surfaces. Germs that cockroaches eat from decaying matter or sewage are
protected while in their bodies and may remain infective for several weeks
longer than if they had been exposed to cleaning agents, rinse water, or just
sunlight and air.
Good sanitation and habitat reduction, along with vacuuming, surveillance, a
baiting program, and some sealing of cracks can usually quickly reduce or
eliminate a cockroach population. A trained, certified Pest Management
Professional (PMP) has the knowledge and tools to evaluate the situation, guide
and advise on sanitation improvements, and accomplish the remaining
steps.
Recent medical studies have shown that cockroach allergens cause lots of
allergic reactions in inner city children. They were even shown to cause asthma
in children. These allergens build up in deposits of droppings, secretions,
cast skins, and dead bodies of roaches.
Adequate control of cockroaches is needed in such settings to help prevent the
build-up of dangerous concentrations of their allergens. Where large cockroach
populations are already well established, and in older buildings, or in
buildings which allow roaches to easily move between rooms or apartments, very
good sanitation by one occupant will not solve the problem. In those cases, the
help of a trained, experienced, licensed pest management professional will
probably be needed to reduce the problem, and effectively work toward
eliminating the roaches.
Profiles of the four main urban pest cockroaches.
1. German Cockroach. The
German Cockroach, Blattella germanica (L.), is about 5/8-inch (16 mm) long,
light-to-medium brown with two dark parallel stripes the long-way on the
pronotum. Females are slightly darker, and have wider bodies, and more rounded
abdomens than males. Nymphs have two dark parallel stripes the whole length of
their bodies. They breed all year round indoors in humid places at about 70oF (
21oC ). They produce 30-40 eggs in a capsule (`otheca) approximately three
months after they first hatch, and then produce another capsule about every 28
days after that.
2. American
Cockroach. The American Cockroach, Periplaneta americana (L.), is sometimes
called the “Palmetto Bug” in tropical American areas. They are the largest of
the house-infesting urban pest cockroaches at about 1.5 inches (38mm) long,
with full-sized reddish brown wings and a light margin completely around their
prothorax. The females have larger, heavier bodies, and the males have two
obvious pairs of stylets at the tip of their abdomen. They often live in sewers
and live outdoors in warm areas like Florida or southern California. They can
thrive in underground steam and utility tunnels in Alaska. Under good
conditions, it takes an American roach about nine to ten months to grow from
hatching to maturity. After another 45 days, each mated female can produce an
egg capsule containing 16 eggs every four to five days until she has produced
more than 50 of them. The female usually glues her egg capsule into or onto
some partly hidden spot. These are the most common cockroaches on sea-going
ships. They have been noted to chew off the eyelashes, eyebrows and toenails of
humans.
3. Brown-Banded Cockroach.
Brown-Banded Cockroaches, Supella longipalpa (Serville), are very slightly
smaller than German cockroaches (about ½-inch; 13 mm long). They have two
lighter bands across their dark brownish bodies. Males have full wings, which
reach beyond the tip of their rather pointed abdomens, but females have
underdeveloped wings, much shorter than their broad, rounded abdomens. The lighter
band markings are much more distinct in nymphs than in adults of either sex.
Within a room, these roaches tend to prefer warmer, drier, and higher locations
than do any of the other urban pest roaches. They are often found in upper
cabinets or in other rooms than the kitchens (food preparation areas) or
bathrooms. Under good conditions of moderate humidity and warm temperatures of
about 80oF ( 27oC ), these roaches can develop from hatching to adult in around
95 days. The females can begin producing egg capsules containing about 19-20
eggs after about 70 more days. This species does not require as much moisture
as any of the other three urban pest cockroach species.
4. Oriental Cockroach.
Oriental Cockroaches, Blatta orientalis (L.), are large very dark (almost
black, but sometimes dark reddish-brown), shiny cockroaches which live in
sewers and similar wet, decaying organic matter. They are sometimes called
“water bugs” because they come out of drains, and “black beetle cockroaches”
because of their smooth, dark bodies. Males are about 1 inch long, with wings
that cover only about ¾ of their abdomen; females are about 1 ¼ inch long, and
have only short stubs of wing pads. They survive best at lower temperatures
than the other three urban pest roach species, preferring a range of 68 to 84oF
(20 to 29oC), and are seldom found in warmer states in the U.S. They grow
slowly, needing more than 200 days to go from hatching to adult, and females
take another 60 days to produce their first egg capsule of 16 eggs. They may go
on to produce 8 to 10 egg capsules at a rate of about one every 30-40 days,
depending on temperature and moisture conditions.
Ticks Prevention and Protection
Removing Ticks
Community Responsibility
The greatest defense against mosquito-borne illness is you. The homeowner. The
parent. The average consumer.
Since one of the most widely recognized mosquito-borne illnesses—West Nile
Virus—was first detected in the U.S., the potentially fatal disease has spread
across the country from Pennsylvania to Washington state. Forty-one states and
Washington D.C. have confirmed cases of West Nile.
Not all communities provide municipal mosquito management. But only a concerted community-wide effort can properly manage these pests and reduce the risks associated with them. Every town. Every neighbor.
Diseases Transmitted by Mosquitoes Mosquitoes transmit several human diseases—all of which can be fatal—including:
How You Can Help Prevent the Spread of Mosquito-Borne Illnesses
Where To Find a Local PMP The National Pest Management Association
(NPMA) has developed a national online consumer referral service for homeowners
in need of a professional pest control company. The referral service can be
found on the NPMA website at www.pestworld.org/homeowners. Through this consumer referral
service web link, homeowners can request that a pest control company contact
them and address their specific pest problem. The request is then sent to
professionals in the homeowner’s geographic area. Pest control companies
respond to homeowners via email with a brief description of their services.

Bees, Ants, Beetles, Termites: Are They Chewing Up Your Home? They’re big and scary
and look like bumble bees – inch-long carpenter bees with a shiny abdomen and
yellow thorax. When humans approach, males may angrily hover a short distance
in front of a person’s face or buzz around their head. People stay clear of
them. Most don’t know it’s only an act, flying around the nest playing guard.
Nature has left this male ill-prepared: he has no stinger. Only the female
can sting. It’s a potent sting but she rarely uses it. For homeowners, a
bigger but little-known danger lurks. Carpenter bees are wood-destroying
insects that can cause serious structural damage if not caught in time and
treated. Other pests that can eat through wood include: termites, carpenter
ants, and powder post beetles. If any of these
organisms has established a nest in the wood of a structure, homeowners
probably will need the services of pest management professionals to help
determine and implement an effective plan to control them and prevent
re-infestation. This is especially true if any form of chemical control is
needed. This plan is likely
to be an Integrated Pest Management (IPM) approach, according to Dr. Mark Lacey,
Director of Technical and Field Services for the National Pest Management
Association (NPMA), a trade group representing professional pest management
companies in the U.S. and around the world. IPM is a
decision-making process that anticipates and prevents pest activity and
infestation by combining several techniques or materials to achieve long-term
management, such as structural repair, maintenance, biological and mechanical
control techniques, and pesticide application. Lacey said IPM
differs from traditional pest management in that it employs an approach that
requires more participation by the homeowner to achieve long-term pest
management. “Since their home’s
likely their biggest investment in their lifetime, most homeowners are more
than happy to take the time and effort needed to implement the pest
management professional’s recommendations for an effective program,” he
said. Professional pest
management can be important because the untrained eye often cannot see the
structural damage caused by carpenter bees, carpenter ants, powder post
beetles, or even the dreaded termites. Everyone knows about
the dangers of subterranean termites, which cost in excess of $2.5 billion in
treatments and damages each year as they tunnel their way through structures.
Damage to affected wood may be so great that the building may crumble or
collapse entirely. Not generally known
is that there are seven species of carpenter bees throughout the U.S. They
get their name from their ability to drill through wood and nest in
near-perfect holes of about one-half inch in diameter. The hole is usually
located on the underside of wood surfaces, including siding, soffits, decks,
overhangs, fence posts and window frames. They tunnel aggressively in cedar
siding. Although the hole
only appears to be only an inch or two deep, it rarely ends there. The female
bee takes a right-angle turn and bores a gallery anywhere from four to six
inches in a new gallery and up to 10 feet for galleries developed and used by
several bees. This channel serves as a main corridor in which they usually
wall-off smaller chambers a few inches long to hold their eggs and developing
young. Female carpenter bees
will drill galleries in a wide array of woods, but prefer weathered and
unpainted woods. Pressure treated lumber in decks won’t stop them. Carpenter bee control
consists of treating each individual gallery with an appropriately labeled
pesticide. Aerosol injection systems are probably the most efficient, safest
and quickest way to treat galleries, especially when on a ladder. Similarly, carpenter
ants get their name from hollowing out galleries in wood as nests. They can
do serious damage to buildings when they cut extensive galleries in
structural wood. The first sign of an
infestation may be seeing several sizes of worker ants crawling along a
countertop, or small piles of ragged “saw dust” mixed with dirt particles,
fragments of insulation, and insect body parts (frass). Each pile of frass is
usually directly below a small hole in some wooden part of a cabinet,
windowsill, or structural part of the building. There are nine
species of carpenter ants throughout the U.S., with as many as four or five
species commonly seen in some places. All species mainly attack wood which
is, or has previously been, wet and damaged by fungi. Carpenter ants can be
hard to control. It usually requires a trained professional to detect the
telltale signs of typical carpenter ant debris, gallery openings, foraging
trails, or typical gallery cutting sounds. Just controlling the ants you see
crossing the floor won’t help. Then there are
lyctids, commonly known as powderpost beetles because their larvae produce a
very fine, powderlike dust (like talcum powder or flour) in their galleries.
There are about 11 species in the U.S. Besides piles of
dust, another sign of damage and infestation are their round exit holes.
Female lyctids lay their eggs in exposed wood pores, cracks or crevices.
Lyctids attack the sapwood and only that of hardwoods, usually less than 10
years old. Lyctids usually
attack oak, hickory, and ash, and will attack other native and tropical
hardwoods. They also often attack bamboo. For control, a local
treatment or fumigation may be used depending on extent of infestation and
the preferences of the homeowner. |
