How do l recognize an earwig?
The most common earwig in Canada is the European earwig.
It is easily identifiable by forceps-like appendages at
the base of the abdomen. The flat, elongated body
measures 12 to 19 mm (1/2" - 3/4"). Males are larger
than females. Color 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, baseboards 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 defense and courtship and will not harm humans.
What are their breeding habits?
Do they multiply quickly?
The female earwig lays broods of 300 eggs, twice a year,
which hatch in about three months. Eggs are laid in
small batches 5 to 8 cm (2" - 3") 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 soon number
in the thousands.
Do earwigs die off in cold
months?
No. Earwigs become dormant during the winter, either as
adults or eggs and sometimes tunnel as deep as 1.8 m (6
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 outdoors. 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.
