Ants are a concern for many Bainbridge Island homes and businesses. Most ant species, such as Odorous House Ants (or Sugar Ants), are more of a nuisance than immediate threat, secreting an unpleasant smelling odor. Other species, however, such as Carpenter Ants, are classified as Wood Destroying Insects and can cause major damage to structural components of buildings.
Spiders are another concern for the residents of Bainbridge Island. While most spiders in the Pacific Northwest are harmless unless provoked, they are still generally not welcome guests. Especially common in wooded areas as well as near large bodies of water, Spiders will make their nests near overgrown vegetation close to buildings, feeding off local insect populations.
The most common pests found in the Pacific Northwest are rodents. Rats and mice can be extremely persistent and difficult pests to exclude. These tenacious pests are quite common in wooded areas, and will often make their ways into homes by burrowing into walls, crawlspaces, and even attics. Aside from causing damage to walls, wires, and various structural components, rodents are known vectors for diseases, such as Salmonella and hantavirus.
