Peach Earwigs & Trees

Because they feed on aphids in some garden situations, earwigs are considered beneficial insects, but in trees they feed on the delicate fruit and cause substantial damage. The species of earwig that hurts peach trees would be that the European earwig (Forficula auricularia). The insect is all about 3/4 inch long and reddish brown in color. It’s easily recognized by means of a pair of appendages in the rear end.


Earwigs feed on fruit and tree leaves. Leaves may have signs and jagged holes around the edgesbrought on by caterpillars. To differentiate the harm start looking for webbing and frass, which is excrement that resembles fine sawdust. Both of these symptoms indicate that the problem is caterpillars and not earwigs. Fruit will have narrow gouges.


Trapping makes the usage of insecticides unnecessary and is an effective way to control earwigs. Cubes are made by low-sided cans like tuna or cat food cans with a half inch of oil at the bottom. Use vegetable oil or fish oil with a couple drops of bacon grease as bait. You can use pieces of tube such as sections of a water hose, rolled newspaper or cardboard; earwigs will come across these hiding places without the use of bait. Place the traps just before dark and empty them into a bucket of water in the daytime. Continue putting traps till you are no more grabbing earwigs.

Hiding Places

Practice decent sanitation to eliminate hiding places like fallen leaves, weeds and debris. Earwigs also conceal in mulches and groundcovers as well as ivies. Suckers that rise from the base of the shrub may also give refuge. Earwigs can hide in cracks and crevices in the bark of trees that are peach. From the lower trunk, carefully scrape off the loose, outer bark on trees.

Additional Controls

Earwigs conceal in cool places at night. In arid, Mediterranean climates, the insect is encouraged by irrigation practices. Water trees early in the day when earwigs find a moist hiding place so the surface of the soil around it and the tree have plenty of time. Coating the trunk of this tree with a substance designed to snare insects prevents earwigs from scaling the tree.
