For many homeowners, the garage is a cluttered storage space where trash and other unwanted items accumulate. Such a disorganized environment is the perfect place for insect pests like crickets to inhabit. You may have a full-blown cricket infestation before you even know they are there. Once you have determined that you have a cricket problem there are several things you can do to take back control of your garage. The first step you should take, however, is to ensure that once you get rid of the crickets they can't get back in.
Remove as much garbage and clutter from the garage as possible to reduce the number of places crickets can hide and nest. If possible, store all boxes and other items on wall-mounted shelves to keep them up off the floor where they will be less accessible to pests.
Clean up the area around the outside of the garage to make it a less enticing environment for crickets. Cut back any overgrown weeds or tall grasses and remove piles of bricks or firewood.
Repair any cracks and holes in the door frame and window sills as well as gaps in the foundations and other places where crickets might be able to enter the garage. Use caulking around doors and window sills and fill in gaps in the foundation with the same material of which the foundation is made.
Spray a chemical insecticide around the outside of the garage, targeting the ground and the foundation all the way around the building. Select an insecticide containing either chlorpyrifos or diazinon to achieve the best results.
Place glue traps inside the garage in the corners as well as under or around any shelves and appliances.
Spread poisoned cricket bait on the lawn around the garage using a push spreader. Consult the manufacturer's instructions to determine whether watering is necessary after the bait has been spread.
