How to Kill Dermestid Beetles
- 1). Lay out sticky traps in areas where you notice adult beetles or larvae. Place traps near cracks and windowsills where beetles may come in. Some traps contain pheromones that attract dermestid beetles.
- 2). Sweep up any dirt and debris and dust beetle-infested areas thoroughly to eliminate feeding sources. Vacuum carpeted areas and dispose of the canister contents or vacuum bag immediately. Eggs and larvae can live inside the vacuum and may cause a reinfestation if you do not dispose of the vacuum's contents.
- 3). Wash clothing, bedding and any other washable fabrics in hot water to kill eggs, larvae and adult beetles.
- 4). Spray highly infested areas with insecticide specified for use against dermestid or carpet beetles. Do not spray clothing or bedding. Test small areas of fabric, rugs and carpet before fully applying insecticide to make sure the product will not stain or discolor the fabric.
- 5). Take large items, such as mattresses, to a professional pest control service to fumigate them if they are infested with dermestid beetles.
