Most people know Field and House crickets. Field crickets are brown and in some cases, black in color. House crickets look the same but are much lighter. They are normally tan to light brown.
Both species will live in and around the home. Both develop the same way.
FIELD CRICKET BIOLOGY
Adult cricket females can lay several hundred eggs. Once their eggs hatch, the young develop through a series of instars before fully maturing. However, young can do just about everything adults can. It takes a year for a generation to fully develop.
Since one female can lay hundreds of eggs, initial activity is usually not noticed. Once eggs hatch and migrate around a home, populations will quickly grow. In the spring, expect to see small field crickets. As the summer goes by, these will grow larger and larger. By fall, adults will be foraging into structures looking for a warm place to spend the winter months.
FIELD CRICKET NESTS
Field crickets feed on just about anything. This includes dead insects, live insects, silk, wool, man-made fabric, paper, wood, and just about anything we eat. Typically they’ll nest close to food so keep this in mind when trying to locate local nests.
Field crickets can make the most from a compost pile and will readily nest anywhere garbage accumulates. You can also expect to have them nesting around moist areas where water accumulates or where mold and algae may be growing.
FIELD CRICKET PROBLEMS
Field crickets are a pest for several reasons. First, they can destroy wallpaper. Field crickets love to eat the glue which holds wallpaper onto walls. If they have their way, they will continue to feed in this area eventually consuming the wallpaper itself. This usually allows access to furniture, drapes, rugs and clothing.
In addition to the damage field crickets do, they can also make a lot of noise. Field crickets living in areas behind the home or in the distance provide a natural sound of nature which people like. Once these same field crickets move into your home, this singing immediately becomes unbearable. Expect it to be loud, continuous and to occur at night. Field crickets are nocturnal and do their feeding and singing when it is dark outside. This makes treating for them a little more difficult but there are ways to keep them at bay.
FIELD CRICKET CONTROL OUTSIDE USING BAIT
There are two approaches to control these field crickets in and around the home. First, you must realize they originate from outside. This means you need to treat outside to keep their numbers in check. Once populations grow to excessive numbers outside, expect to have some migrating into your home.
The first type of cricket control program is somewhat passive and yet will work if the infestation has just begun. In recent years, several cricket baits have been introduced which work well on field crickets. There are two which will provide control for populations which are still small.
Use SCATTER BAIT outside around the home, in the turf and in flower beds. This granule works well for ants, but field crickets are on the label as well and crickets like cave, camel-back and field crickets will readily eat it. Try to sprinkle small amounts around the home creating a 5′-10′ wide band of treated area. The granules are small and only a little is applied with each sprinkle. The granules will pretty much disappear but rest assured the field crickets will find it.
A 1 pound bag can cover up to 500 sq/ft and will last 2-3 months even in harsh damp environments.
