It is once again the time when insects inadvertently enter homes and buildings from the surrounding landscape. Common accidental invaders include boxelder bugs, multicolored Asian lady beetles, pine seed bugs, spiders, hackberry psyllids and elm leaf beetles.
Accidental invaders are generally harmless to people and property.
They do not feed on people, pets, houseplants, stored products, or furnishings. They cannot sting and they do not carry disease. Accidental invaders cannot reproduce indoors. They are nuisances just by their presence, especially when they occur in large numbers. Residual insecticide barriers can supplement pest-proofing and may be applied by a professional pest control firm or by the homeowner.
