Fill a bucket with 1/2-gallon of hot water and 1 tablespoon of liquid dish soap. Pick the beetles up by hand and put them in the bucket. The beetles will drown in the soapy water. This will work if you have a few beetles in your home.
Place several sticky traps made for bugs and insects around your home where you notice the beetles congregating. Replace the sticky traps once they become full. Continue until the sticky traps remain free of beetles.
Vacuum up the beetles with the hose attachment of your vacuum cleaner. Remove the vacuum cleaner bag once you have finished and discard it in a trash can with a secure lid.
Set out a few pheromone traps to lure the beetles. Once the beetles enter the traps, they will get stuck and be unable to leave. Replace the traps until you no longer notice any beetles in your home.
Spray a pyrethrum-based insecticide directly on the beetles. Pyrethrum is derived from all-natural plant ingredients and is much safer to use indoors than chemical insecticides. The beetles will die instantly once sprayed.
