Common Pests

Sugar Ants

There are three common ants in the Northwest. Odorous house ants are often called “sugar ants” and be identified by a coconut odor emitted when squished. There can be as little as a few hundred to hundreds of thousands to MILLIONS in one colony! (Referenced by Grzesiek Buczkowski Purdue University, 2/28/15) 

Carpenter Ants

Carpenter ants are a wood destroying organism. They are identified by size and body parts and are usually the largest of ants. Colonies can range from 25 to 100 thousand! (Source: Mallis Handbook 9th Edition). 

Pavement Ants

The third is pavement ants. They are identified by evidence of soil piles left around sidewalks and driveways. Control measures are a combination of a thorough inspection, exclusion repairs along with interior and exterior applications. There is no silver bullet to eliminate ants. Ongoing applications help keep them out of structures.

Rats and Mice

Rats and mice are located throughout the Northwest. They are referred to as commensal, meaning to share the table. In other words, they live where we live! The Northwest has three common species. They are the typical house mouse, the Norway rat and the roof rat.  Rodent infestations are usually discovered through damaged foods and fecal droppings found in structures. The first step in elimination of rodents is a complete inspection to identify their entry points. The elimination of entry points helps to reduce future infestations. After eliminating the entry points a two-step trapping and baiting protocol is implemented until infestation is eliminated. 


The US has about 3500 species of spiders! (Mallis handbook ninth edition) The 3 most common of concern are the brown recluse, the black widow and the hobo spider. The brown recluse is unable to survive in the Northwest and is not common. The black widow is found but not too common. The hobo spider is the most common. It is active from June through September and is considered non aggressive. (Herb C. Field at Entomology Services Inc.) Most spiders around structures are not aggressive. Elimination is achieved by mechanical removal of webs and contact applications.

Stinging Insects

There are three common stinging insects found in the Northwest. Paper wasps are normally found in elevated areas and make “paper” nests. Hornets are the largest and make large “paper” nests in elevated areas as well. Yellow jackets are the most aggressive of all three. These are usually found by accident when they “attack” a passerby. They are common in the ground and are discovered after they “attack” the unsuspecting. Elimination the stinging insects consist of finding and removing the nests. Residual applications help prevent future infestations.

Occasional Invaders

Millipedes, centipedes, silverfish, pill bugs and earwigs are called occasional invaders. Regular applications help to keep their population reduced and out of to edit text, or drag to move.

Animal and Wildlife Removal: A&R Pest Solutions is not a licensed wildlife trapping company. There are times when an animal finds its way into a structure through access points. We inspect your structure to determine how the animal got in and try to remove it. Once the animal has left the structure we encourage access points be repaired and secured to prevent animals from re-entering again. This can be obtained by doing a thorough inspection of the structure.

beforeandafterCrawlspace Clean out

One of the most common places pests infest is crawlspaces. Rodents, opossums, squirrels, raccoons and even cats can create a mess in a crawlspace. They pull insulation from sub-flooring, tear apart your plastic covering, damage heating ducts, make nests and leave feces and urine throughout the crawlspace. A&R provides services to correct these conditions along with repair recommendations to prevent future damage.
