EARWIG
Description: Beetle-like insects red-brown, 3/4 inch long, easy to identify by their prominent pair of forceps at the rear of the body.
Habitat: Found occasionally in lawns, they breed in piles of lawn clippings or other trash and feed on many types of vegetation. They hide during the day and forage at night.
Damage, Symptoms: Contrary to superstition, they do not attack the ears of man. They do attack and destroy flowers and garden vegetables. Some types create a nuisance by invading the home.
Nonchemical: Remove unessential plant debris, mulch, and boards from around buildings. Establish a zone of bare concrete or soil which will dry out. Indoors: Remove by vacuuming. Caulk cracks and crevices around windows, doors, and in the foundation.
EARWORM
Description: Color varies from brown, green or pink with stripes along the side and back. At the adult stage they turn into moths that are most active at night.
Habitat: Most proficient in tomatoes and sweet corn.
Damage, Symptoms: They destroy the vegetables by eating and burrowing in them. Damage is worst in warm, coastal areas.
Vegetable: Apply carbaryl to late-maturing tomatoes 3 to 4 times at 5- to 10-day intervals from small-fruit stage. Apply at fresh-silk stage to early and late corn every 2 days 4 to 5 times.
EASTERN TENT CATERPILLAR
Description: Black in color with thick, tan hair and white stripe down the back. May also be characterized with blue and white markings on the back.
Habitat: Prefer fruit trees such as cherry, apple and crabapple.
Damage, Symptoms: Cause eye sores with silky nests they make in between tree limbs and branches.
Chemical: Spray with acephate, carbaryl, malathion or Bacillus thuringiensis when nests are first noticed. Remove nests and destroy.
ELF LEAF BEETLES
Description: About 1/4" long, oval and yellow to olive green in color. They have dark stripes down their wing covers and dark spots behind the head.
Habitat: In warm weather they live on elm trees where they feed on the leaves, but move into buildings when cold weather arrives. They then cause a nuisance when they try to get back outside when warm weather arrives again.
Damage, Symptoms: Though they don't cause any damage indoors, outdoors their leaf chewing can change the appearance of elm trees.
Chemical: Spray nearby Chinese elm trees with carbaryl 50% wettable powder during the summer to reduce the number of beetles that come into homes in the fall.
Nonchemical: Seal cracks and crevices around windows and other openings to prevent entry. Indoors: Remove by vacuuming.
