Opossum Control

Opossums are an invasive species brought to our area in the early 1900's as pets. The first official siting of an opossum in WA state was in the city of Kelso in 1947 by a University of Washington Biologist. However locals clam that the animals have been around since the late 20's. Official sightings have continued to move in a northerly direction at the rate of about 5 miles per year since the first official sighting. They are typically more active at night. Opossums are the only marsupial in North America. They are among the most silent animals in Washington State, but when threatened they may hiss or growl.

Opossums will break into attics, chimneys, and crawlspaces. They typically will do damage to heating ducts, insulation, and will also cause damage entering the structure. They also will make large toilet areas throughout whatever area they are living in, which does create a very unpleasant smell.
