Earwigs

How do I recognize an earwig?

The most common earwig in Canada is the European Earwig. It is easily identifiable by forcep-like appendages at the base of the abdomen. The flat, elongated body measures 12 to 26 mm (1/2″ to 3/4″). Males are larger than females. Colour ranges from reddish to dark brown.

Do earwigs cause damage?

Yes. Outdoors, earwigs are a real threat to plants, feeding on the roots of flowers, vegetables and shrubs. Indoors, they are more of a pest and will eventually die out.

When are earwigs most common?

During the warm summer months, particularly June,July and August.

When am I most likely to see earwigs?

Earwigs are nocturnal and are most active at night.

Where do you find earwigs?

Earwigs prefer a dark, moist habitat beneath stones, boards, sidewalks and debris. In the home they crawl under rugs, cushions, base boards and dark, damp crevices, especially in basements.

Are earwigs hazardous to humans?

No. Their forceps may look dangerous, but will inflict nothing more than a slight pinch. These forceps are used for defence and courtship and will not harm man.

What are their breeding habits? Do they multiply quickly?

The female earwig lays broods of300 eggs, twice a year, which hatch in about three months. Eggs are laid in small batches two to three inches beneath the soil. The female guards the eggs and newly hatched young until the first molt, when they leave the nest Since they multiply fairly quickly, an infestation can number in the thousands.

Do earwigs die off in cold months?

No. Earwigs hibernate during the winter, either as adults or eggs and sometimes tunnel as deep as six feet below the soil surface to escape the cold. For this reason, if an earwig problem is left unchecked, they will return next season in increased numbers.

Can weather conditions affect the size of an earwig infestation?

Yes. Since they prefer dampness, a moist spring will encourage larger numbers of earwigs out doors. For this reason, if the summer months are dry, earwigs will enter homes and buildings in search of moisture.

Can I do anything to prevent an earwig infestation on my property?

Yes. Since earwigs like moist, dark places, try to eliminate debris around your property, such as grass cuttings, mulch patches and wood heaps.

If I have an infestation of earwigs, what can be done to eliminate them?
