To get rid of a wood cockroach problem in the house, avoid storing firewood inside, seal all cracks and crevices, repair screens and turn off lights during the mating season. If you find a stray cockroach in the home, sweep it up with a broom and dustpan, and toss it outside.
Wood cockroaches eat rotting trees, leaf litter and other decaying organic matter, so keep woodpiles off the ground and away from the home. Use plumbing tape, caulking or foam solutions to seal off any holes or cracks in the home, especially in problem areas such as the kitchen or bathroom. At night, close the blinds or keep lights off to avoid attracting males, and limit porch light use during May through June when cockroaches are mating. Fix any holes in the door and window screens, and keep weather-stripping in good repair. Fix leaks to remove sources of standing water, and keep exterior plants trimmed.
Wood cockroaches live and breed outdoors and only enter the home in search of food or water, so chemical control measures such as spraying and cockroach fogging generally aren't necessary. Household pesticides are also not very effective against wood cockroaches. Preventing them from entering the home is the safest and most effective control option.
