Cluster Flies

Cluster flies start to appear in early March and will continue inside the house until the end of April. Cluster fly populations were very high in the fall of 2015 and we expect they will be again this spring.

Paper wasps

Paper wasps which over winter in your attics, walls and soffit areas become active with the first warm days of March and activity continues on the outside of the house throughout the summer into late fall. The European paper wasp which is a fairly recent introduced species and had become more numerous than our native paper wasp seems to have been severely affected by the last two harsh winters and their numbers are greatly reduced.

Box Elder Bugs

Box elder bugs start to appear on the first warm days in March and will continue until May. They have not been as numerous for the last 2 years due to the previous cold winters but were starting to reappear again last fall.

Pine Seed Bugs (Western conifer seed bugs)

Pine seed bugs also known as ‘stink bugs’ become active on the first warm days in March and continue into May.

Lady Bugs

Lady bugs start appearing in mid-March and continue well into May. They were more numerous in the fall of 2015 than they had been for at least the last 5 years.

Carpenter Ants

Carpenter ants can become active in early spring sometimes even in January and February and activity may continue well into late spring. Activity of these ants in the winter or spring before the snow melts indicates that the colony is located within the structure of the house.
