Most occasional invaders enter structures because outside weather conditions become too hostile for their survival. Learn more some of the pests that fall into this unique category.
1.The Stink Bug
Brown marmorated stink bugs are named for the odor they emit as a defense against predators. Adult stink bugs enter homes in the late fall to seek shelter from the winter weather. Similar to boxelder bugs, they often congregate en masse on the sides of buildings.
Earwigs get their name from the myth that they crawl into people’s ears when they are sleeping. Earwigs tend to gather in large numbers outdoors, where they are often found under piles of lawn debris, mulch or in tree holes. They can occasionally enter homes through small cracks or rips in window screens.
Silverfish hide during the day, often in tight cracks or crevices. They are known to infest paper products, such as wallpaper, book bindings and envelopes. They also eat linen, rayon and cotton fabrics.
Pillbugs are often called “rollie-pollies” because they roll into a ball when disturbed. Similar to other occasional invaders, pillbugs live in moist locations and are usually found under damp objects outdoors such as trash, rocks, or decaying vegetation, where they remain hidden during the day to reduce water loss.
Centipedes are sometimes called “hundred-leggers” because of their many pairs of legs. They are typically found in areas of high moisture, such as bathrooms and basements. If handled roughly, some larger species can inflict a painful bite. However, most centipedes don’t pose health or property threats.
House crickets are known for their loud chirping which is caused by rubbing their front wings together to attract females. During warm weather, house crickets typically live outdoors and are especially fond of garbage dumps. They are also attracted to electric lights in larger numbers.
Ladybugs are also known as lady beetles or ladybird beetles. Most species of this beetle family are highly beneficial insects, but some enter homes in the autumn and can become a nuisance. Most ladybug species do not pose a health threat to humans; however, the multi-colored Asian lady beetle is known to aggravate asthma and cause allergic reactions in some people.
