IDENTIFYING EARWIGS IN THE HOME
There are three common earwig species:
– European Earwigs:
The most commonly found species in the U.S., these earwigs have long antennae and noticeable pincers. They are brownish in color and can sometimes invade homes or gardens in large numbers.
– Red-legged Earwigs:
Dominant primarily in the south, these dark brown earwigs have yellow-tan undersides. They can also be seen in large populations nearby residential dwellings.
– Striped Earwigs:
More commonly found outdoors, these black and tan bugs have especially large rear pincers.
All three earwig species are primarily herbivorous, living on a diet mostly composed of rotting plant material. They enjoy compost piles, fallen leaves and unattended garbage. Some earwigs are capable of flight, but they generally prefer to crawl to get around to find food resources and nest.
Earwigs usually enter the home in search of shelter or water. Dry Arizona summers and drought conditions are one reason that earwigs might be found indoors. They are commonly seen in kitchens and bathrooms where water is most plentiful.
Earwigs are not a social insect like ants or wasps, but they can arrive in large numbers if the conditions are right. Their alarming appearance and occasionally large numbers make these pests a nuisance for residential homes and business owners. It is the better idea to get rid of them once they are found inside, as they will grow in numbers unless stopped.
