The most common spiders in the Pacific Northwest are. The Aggressive house spider sometimes called the Hobo spider is a member of the (family Agelenidae) commonly called the funnel-web spider or funnel weavers. These spiders build funnel webs in dark moist areas, often in basements, and sit in the mouth of the funnel waiting for prey. Wolf Spiders (Family Wcosidae) These are large, dark, and somewhat hairy spiders that hunt down prey on the ground. They often wander into homes in the cool autumn. Jumping spiders (family Salticidae) These compact, active and usually colorful spiders often are found on window sills and ceilings where they stalk and pounce on unsuspecting flies and gnats Orb weaving spiders (family Araneidae) These belong to the largest family of spiders. All construct the circular, flat, wheel-like web in which they trap flying insects. Sheetweb spiders (family linyphiidae) These small drab spiders engineer dew speckled webbing that enshrouds fields and forest in the early morning. Hackled Band Weavers (family Amaurobiidae) A robust spider. Is common crawl-space inhabitant of houses in western Washington.
You really have to work to get bitten by a spider, because they do not want to bite you. Spiders tend to avoid people and have no reason to bite humans because they are not bloodsuckers and do not feed on humans. When spider bites do happen, they will tend to occur because the spiders are surprised by a person reaching into a glove or rolling over on a spider in your bed. Even then however, the majority of spiders are not toxic to Humans. Many spiders are not even cable of piercing human flesh. The Black widow and Brown Recluse are not native to the pacific Northwest.


There are several types of fleas, but the most common is the Cat Flea. Fleas are very small brown in color and range in size from 1/12" -1/6" long, and are wingless, latterly flattened, and have piercing/sucking mouth parts. A flea can jump 7 to 8 inches vertically and 14 to 16 inches horizontally. Fleas go through a complete metamorphosis (Egg, larva, pupa, & Adult) After each blood feeding female fleas will lay 4-8 eggs at a time. Eggs hatch in about 10 days, pupal stage could last up to 20 weeks. Development from egg to adult requires from 16 days to a year or more. Vibration will stimulate and speed up this process. Adult Fleas feed on blood with their piercing/sucking mouth parts. Typically, they will seek a blood meal within 2 days of becoming an adult. Many people don't even know they have a flea problem until they and their pet are away from the house for an extended period of time. This happens because the fleas will get hungry while the host is away. This will cause them to become highly active when returning to the home.

Stinging Insects


Social Wasp (yellow Jackets, Bald Faced Hornets, Paper Wasp) Social wasp have the typical wasp body type that features a very distinct head with the chewing mouthparts, short-elbowed antennae, and large compound eyes. Paper wasp are colored yellow, black, brown, and red, depending on the species, with 1/4"4" long slender bodies. They build paper nest of a single comb no paper covering. Yellow Jackets usually are marked with bright yellow and black pattern. They appear to be hairless and are about 3/8"-5/8" long. Bald Faced Hornet is similar in appearance to the yellow jacket except that it is black and white in color and S/8"-3/4" long. Yellow Jackets and Hornets build their paper nest in stacks which are surrounded by a paper envelope. Yellow Jackets usually build their nest below ground and in other protected locations. Bald Faced Hornets build their nest in trees and on the sides of buildings. Social wasp contains three individuals, or castes: Queens, workers, and males. Fertilized Queen will overwinter in a protected area until spring. In the spring the queen emerges and builds a new nest. In about 30 days the first workers emerge. By summer there is a great increase in the number of workers and the nest expands rapidly. By late summer the worker populations are at their peak and the workers become pestiferous; the production of the new queens and males begin. In early fall, the new queens and males emerge. The colony starts to decline. The new males and queens mate, the males die and the fertilized queens seek sheltered places to overwinter. The nest is gradually deserted and the nest will disintegrate with the onset of cold, wet weather. (If nest survives the winter it will not be reused.) The cycle repeats the following year.


The Bumble Bee is a big hairy black and yellow bee. Their size ranges from %"-1 /2" in length. There are over 200 types of Bumble Bees in the world. Bumble Bee nest are typically in the ground. Fertilized Queen bees come out of hibernation in the spring and start a new colony in a new location. The first batch of larvae is daughter which are workers, they will immediately start working on building the colony. The queen will continue to lay eggs for the rest of the summer. Towards the end of the summer the queens will start to produce drones and young queens. The young Queens are fertilized by the Drones, then fly off to hibernate. The colony's remaining drones and workers stay in the colony and die during the winter season.
Bumble Bees are very important, beneficial insects for pollinating, and should be left alone unless they are a danger to people or pets.


One of the most Familiar insects in the world is the Honeybee. This member of the insect order Hymenoptera plays a key role in the human and natural world. Honey Bees are normally about 3/4" if in length. Honey is a thick liquid produced by certain types of bees from the nectar of flowers. While many species of insects consume nectar, honeybees refine and concentrate nectar to make honey. Bees make lots of honey so they will have plenty of food for times when flower nectar in not available, such as winter months. Unlike most insects, honeybees remain active through the winter, consuming and metabolizing honey in order to keep from freezing to death. Honeybees are social insects. In the wild they create elaborate nest called hives containing up to 20,000 individuals during the summer months. Domestic hives may have over 80,000 bees. Honeybees work together in a highly structured social order. Each bee belongs to one of three specialized groups called castes. The Castes are Queens, Drones, and Workers. There is only one Queen in the hive. The Queen's job is simple. Laying the eggs that will spawn the hives next generation of bees. If the Queen dies, workers will create a new Queen by feeding one of the worker females a special diet of food called royal jelly. The elixir enables the worker to develop into a fertile Queen. Queens also regulate the hive's activity by producing chemicals that guide the behavior of the other bees. Male bees are called Drones. Several hundred drones live in each hive during the spring and summer, but they are expelled for the winter months when the hive goes into a lean survival mode. Workers are the only bees that most people ever see. These bees are female that are not sexually developed. Workers forage for food (pollen and nectar from flowers). Build and protect the hive, clean, circulate air by beating their wings, and perform any other social functions. These are the only bees that can sting. Males bees do not sting. As the field bees (Older Workers) forage for nectar, pollen sticks to the fuzzy hairs which cover their bodies. Some of this pollen rubs off on the next flower they may visit, fertilizing the flower and resulting in better fruit production. Some plants will not produce fruit at all without the help of honeybees. In the United States alone, it is estimated that honeybees accomplish % of the pollination needed for all fruit produced for human consumption, an estimated $10 billion worth of work each year. Whenever possible you do not want to kill honeybees. The preferred method is to have bee's removed by a beekeeper.



The Pavement Ant Tetramorium Caespitum (Linnaeus) is an introduced species and is one of the most commonly encountered house infesting ant. Pavement ants are 1/16"-1/8" long and vary in color from dark brown to black. They are a two node ant with a 12 segmented antennae.
  • Very little information is known on the Pavement ant colony. Most colonies are located under sidewalks, building slabs, large rocks. It is common to see sand piles and small soil particles in structures near cracks in concrete slabs, foundations or cracks in sidewalks.
  • Pavement Ants feed on a wide variety of food. Sweets, including sugar, nectar, fruits and syrups, but they prefer meats and greases.


The Odorous House Ant (Tapinoma sessile) is a native species, found throughout the United States. It earns its name by producing a foul coconut odor when crushed. Worker ants are 1/16" — 1/8" long and are a brown to black color. They are a single node ant with a 12 segmented antennae.
  • Odorous house ants may mate in nest forming new colonies by budding from the original colony. Colony size may range from 100 -10,000 and may have several Queens. (which makes this a hard ant to control)
  • Odorous House ants travel in trails and prefer sweets


Carpenter ants have several species (Camponotus species) The 2 most destructive species in the Western United States are the C. modoc and the C. Vicinus. Carpenter ants are among the largest ants in north America with workers ranging from 1/8"- 34" long. The modoc Carpenter Ant is black in color while the Vicinus Carpenter Ant varies in color but is usually red and black.
  • Mature colonies may range from several thousand to 15,000 including satellite nest. Carpenter Ants complete their life cycle in about 60 days. Swarmers do not appear in the colony until usually 3-4 years.
  • Carpenter Ants do not consume wood but excavate it to make their nest. This often begins in an area where there is damage from water or wood decay. From here they will expand the nest into sound wood and compromise structural integrity. They will nest in wall voids, hollow doors foam insulation, & fiberglass insulation.
  • Carpenter Ants feed on sugar solutions from honey dew producing insects such as aphids, sweets and the juices from insects they capture.


In the Pacific Northwest there are four cockroach species that may be encountered in structures. The two most common in the pacific Northwest are the Adult Brown Banded cockroach & the German cockroach followed by the American Cockroach, & the Oriental Cockroach.
Brown-Banded Cockroaches are about 1/21" long when mature, light brown in color and have two light yellow brown bands running across their bodies. Nymphs and females are broad when viewed from above, while the male is slender. The males' wings cover the abdomen, whereas the females wings are short, exposing the Abdomen.
Female Brown-Banded Cockroaches produce about 10-20 egg capsules each and could hold 14-18 eggs. The egg capsules get carried for 24-36 hours before they get attached to a protected area. Nymphs then emerge in approximately 70 days, molting 6-8 times before becoming adults within a 90 to 270 day time frame. Adults could live for about 6 months.
German Cockroaches are M"-5/8" long when mature, light brown to tan in color with two dark brown lengthwise stripes on the shield behind the head. Adults are fully winged but rarely fly. Female German Cockroaches produce 4-8 egg capsules each containing 30-40 eggs. The female carries the egg capsule till approximately 1-2 days before hatching then she will deposit them in a safe protected area. Nymphs molt 6-7 times before becoming adults. The process requires approximately 100 days, which allows 3-4 generations per year. Adults live up to 12 months. Because German Cockroaches produce more eggs and has more generations per year than any other cockroaches, a troublesome infestation can rapidly develop.


Most of the woodboring beetles found in structures in the northwest belong to the family Anobiidae, the death watch beetle. The western death watch beetle is responsible for most of the damage to wooden structures along the coastal areas of western north America. People rarely see these insects. Adult beetles range from 2-5 mm long and are reddish to chocolate brown in color. Eggs are 0.5 mm long, white, and teardrop shaped. Larvae are white, c-shaped and 5-6 mm long when fully developed. Pupation takes place just beneath the wood surface.
Adult beetle mate during July and August, and females soon lay 10-30 eggs singly or in groups of 2 to 10 within natural depressions of wood. Eggs hatch in about 3 weeks, and newly emerged larvae bore directly into wood or, quite commonly, leave the oviposition site to find a more suitable place to feed. Anobiids may spend 5 to 6 years or longer in the larval form feeding on wood. In late spring early summer, mature larvae bore tunnels to within a few millimeters of the wood structure to pupate and change into adults. Adult beetles chew a small circular exit hole and emerge. This cycle will continue until all available nutrition has been depleted. Structure-infesting anobiids occur primarily in older homes that have crawl spaces or damp basements. These beetles also infest outbuildings, such as barns or garages. Wooden support timbers, floor joist, and subflooring are commonly infested. The insects will attack new hardwoods (maple, walnut, oak) and softwoods (Douglas- fir, cedar, hemlock or those that have been in service for many years.


Rodent Exclusion is a process of finding entry points where Rats and mice may be entering the structure. After entry points are found they will be sealed or repaired with a method that Rodents will not be able to gain access to the structure again.


Bird exclusion is much like rodent exclusion. Find entry points of birds remove nest if possible, sanitize area of nest and seal off entry point. Bird exclusion may also consist of netting, or bird spikes if required.



Moisture Ants are yellow to a brown in color and are a monomorphic species which means all workers are the same size, and range in size from 3-5 mm long.
Reproductive swarming occurs in the late summer, this is when most people realize they have an infestation. These ants frequently appear associated with rotting wood in houses. While several species may bring moisture into the wood structure to increase damage, the colony initially started in wood in an advanced stage of decay. These ants are not considered structural pest as the problem invariably existed before the colony was established. Moisture ants need moisture to survive. If decayed rotted wood is replaced with sound lumber problem will be taken care of. Chemical control measures act as a temporary solution by killing the ants.


Dampwood have three castes: Reproductives, workers, and soldiers. Dampwood Termites are generally much larger than Subterranean termites. The swarmers may be up to 1" in length. Including their wings and are kind of a mahogany color. The winged reproductive (swarmers) have a pair of long, equally sized wings attached to the last two thoracic segments. The wings are broken off after swarming. Termite antennae have bead like segments. The soldiers of the Dampwood Termite have a large reddish-brown head and large multi-toothed mandibles and are 3/8"-3/4" long. The workers are white to cream color, have dark abdomens and are 1/8"-1/3" long.
In most cases, control can be achieved by eliminating or repairing structurally unsound wood and correcting moisture problems. Spraying alone will not eliminate this pest.
