The western conifer seed bug is a brown insect less than 1 inch long that feeds off seeds and immature cones of conifer trees. Although the insects were first identified in the western U.S., seed bugs are also found along American and Canadian border regions and in the northeast U.S.
Before winter sets in, western conifer seed bugs often make their way indoors where they become pests inside homes and businesses. Though they are nuisances, the insects do not bite or sting. They appear to enter structures along windows and doors. Therefore, sealing these entryways with tight-fitting frames or caulk helps prevent seed bugs from entering. In addition, fireplace chimneys and vents to the outside should be screened.
