Pest NameDescription 
Spiders (non-biting)Spiders (non-biting)To say spiders don’t bite would be in error, since all spiders bite their prey. Most spiders, particularly small species, have not been seen biting humans. However, these 8-legged creatures can be quite a nuisance. The most common nuisance species are orb weavers which construct their vertical webs in the most inconvenient places – in front of entries, over paths between shrubs, in front of windows, etc. Furthermore, their constant defecation can dirty up decks and other surfaces to the extent of making them unsightly. Remember all spiders feed on insects and their relatives so we should consider them beneficial. For more information, see the following publication: Common Spiders of Washington (EM113E) at
