A clean jar filled with molasses or beer diluted with water is effective in trapping and killing household crickets. Lured by the sweet smell, crickets drown in the liquid. Use a vacuum's crevice tool to extract crickets and their eggs from carpet perimeters, baseboards, trim and wall voids.
Organic diatomaceous earth is a talc-like powder created from the fossilized remains of algae; sprinkling it lightly into a carpet can kill crickets inside. Even though it is completely harmless to humans and pets, diatomaceous earth compromises the waxy exoskeleton of crickets, causing them to die of dehydration.
Sticky traps or glue boards designed to trap rats and mice also make good cricket traps when baited with small amounts of cornmeal in the center of each. Place the traps near heat and moisture sources, in corners and along walls.
