Below is a listing of some of the more common
pests we deal with here in the Pacific Northwest. The listing will help you to identify a
possible infestation by giving a description of the pest, an illustration, and some of the
signs to look for. You can click on one of the links below or scroll the page to find the
pest you are concerned with.

Carpenter Ants
Carpenter ants are the most common and destructive wood destroying insects in the
northwest. They are also the largest ants found invading homes. They may range in size
from 1/5 to 3/4 inch. Winged ants or reproductive, (swarmers) are typically found in the
spring and summer months. Carpenter ants are a nocturnal insect, the presence of an
infestation may be heard at night or in the early morning hours. The sounds of carpenter
ants are similar to the sound of rustling cellophane. You may also see sawdust piles
(frass) often in conical piles inside the crawlspace, basement, or inside the home.
Carpenter ants do not actually eat the wood but tunnel it out for nesting purposes causing
extensive damage to the structural integrity of the wood members. |

House Ants
These include dozens of different species of ants. Specific treating including
baiting, chemical treating, nest locating and preventive steps need to all be considered
when eradicating these nuisance ant species. |

Subterranean Termites
The most widespread and destructive termite in the United States, they live
primarily in the soil building exploratory mud tubes above and below the ground. Their
main nutritional ingredient is cellulose which is the hard structural component of wood.
Termite control can be difficult. This is best left to a professional who has the proper
equipment and expertise in dealing with these wood destroying insects. |

Bees & Wasps
Summer and Fall is when these insects are most active. Wasps build paperlike nests
similar to hornets in the ground, landscape timbers, wall voids, attics and under eaves.
Always approach these nests with caution as they are very territorial and can be
quite aggressive. If the nest is visible and within reach, it may be removed easily
depending on its size. However, larger nests or nests located in difficult to reach areas
should be left to a professional. All of our service trucks are equipped with proper
protective gear enabling us to safely remove any wasp. hornet or yellowjacket infestation.
Bees are a very beneficial pollenator. Whenever possible, contacting a beekeeper for hive
removal is a good idea. |

 |
Rats & Mice
Both of these species breed rapidly, tolerate a wide range of conditions and adjust
quickly to changes in their environment. The most successful rodent control programs begin
with thorough inspections. A professional level inspection reveals the extent of
infestation, harborage, rodent entry points, and the safest, most appropriate, and
cost-effective control program for the specific situation. |

Cockroaches
The German cockroach, which is the most common of all the roach species measures
from 1/2 to 5/8 inches in length. They are distinguishable by the two dark brown stripes
that run along the upper part of their bodies. Cockroaches are among the most successful
animals to ever inhabit the planet. The German Cockroach can grow from egg to adult in 36
days. The female carries an egg case which can contain up to 48 individual eggs. Many
business establishments and homes become infested with German Cockroaches when they are
introduced inside infested cartons, foodstuffs, used appliances and other materials.
Cockroaches hide in cracks and crevices by day and emerge to feed at night. Proper
eradication can be difficult. A thorough inspection, baiting techniques, chemical
treating, sanitation, and prevention are all keys to a successful cockroach treatment
program. |

Pantry Pests
These include beetles, weevils and moths. They often infest grain products, seeds,
nuts, bird seed, dried dog food and cereals. The most commonly found pantry pest is the
Indian Meal Moth. These moths wingspan measures about 5/8" with the outer one half of
the wing reddish or copper colored. The key to any pantry pest treatment is to identify
all of the infested food sources. This can be difficult due to the wide variety of foods
these insects will attack. The combination of chemical treating and pheromone trapping is
essential for success in moth infestation elimination. |

Silverfish & Firebrats
Both of these insects look very much alike. However, they are normally found in
different parts of the home. Silverfish are commonly found on ground floors or in
basements or crawlspaces. Firebrats like warmer temperatures and are usually found in
attics and upper levels of the building, especially in structures with wood shake roofs.
These pests often arrive from outdoors living in barkdust, decaying plant matter like
grass clippings, leaves and compost piles. Treatment includes a thorough inspection of the
property, treatment of either attics, crawlspaces or both, crack and crevice treating the
interior, exterior or both, or a combination of all of the above. |

Wood Boring Beetles
These are another type of insect that bores into wood and can be very destructive
to structures. Their emergence holes vary from 1/32" to 1/8" circular holes on
the wood surface. Often they can be recognized by the powder that accumulates below the
holes in the wood. This wood dust resembles the texture of baby powder. |

 |
Fleas
A flea control program should involve treatment of the environment both inside and
outside of the home. Also, infested pets will require treatment by the pet owner or a
veterinarian... |

Spiders
With literally thousands of different species it is often difficult to identify
specific spiders. However, the spider which has been of the most concern in the pacific
northwest has been the Brown Recluse. This spider does not seek to bite people and in fact
most bites are usually accidental. It may crawl into a shoe, bedding or clothing and bite
as a defensive measure when trapped. The Brown Recluse is usually about 5/8" in
length with a leg span of about 1-1/2" in diameter. They are light brown in color
with six eyes arranged in three pairs at the front of the head. The Brown Recluse is also
known as the Fiddle-Back or Violin spider because of a distinctive fiddle shaped marking
on its back. A Brown Recluse bite, if left untreated, can result in an open, ulcerating
sore. It is always best to seek medical attention if you suspect a bite from a Brown
Recluse. Spider control can be very effective by treating crawlspaces, attics, interior
and exterior spaces. |

Squirrels
As much as we all love squirrels they can become a real nuisance when they take up
residence in our attics, crawlspaces or walls. (Often nesting in insulation). They are
commonly heard chewing on electrical wires, wood or stored items normally during daylight
hours. Live trapping has been the most successful in removing these rodents and is also
the method which will cause the least amount of harm. After trapping, we drive them to a
park or other natural setting and release them. Common entry points for squirrels are roof
vents, broken windows, knotholes and construction gaps. Removing food sources like bird
feeders and outdoor pet feeders will help by eliminating a food source and attractant. |

Carpet Beetles
Carpet beetle adults are small 1/16" round normally gray or black. Their larva
are what damages your personal belongings. They are able to digest animal hairs and will
feed on almost any item made of natural fibers, mostly wool, cashmere and silk. The larva
is about 1/4" in length. They are fuzzy and often a light brown, but may vary in
color. They are most commonly found in birds nests, rodent burrows, old wasp or bee hives.
They can also be found in bark dust, mulch, plant bedding and on plants. Treatment
normally requires a thorough inspection, treatment of the outside grounds of the building,
crawlspaces, attics, and interior treating. |

Clothes Moths
Fabric pests like the clothes moth and webbing moth share many of the same
charactastics and behaviors. They are both usually white or cream colored and measure
about 3/8" long. Both of these moths can cause irreparable damage to personal
belongings. They feed on almost any item made of natural fibers, particularly items made
of wool, cashmere and silk. They are also capable of digesting animal hair. Treatment
includes trapping, chemical treating, inspection and washing or dry-cleaning of infested
articles. |
