Control Treatment Plans-How to Get Rid Of Drugstore Beetles
Inspect and Discard: First investigate the infested items and discard them. Every item from the categories listed above needs to be checked. If you find these beetles in your pantry, check the flours, grains, cookies, beans, spices, pet foods, etc. Look for larvae that looks like a white grub. If an item passes inspection, it is a good idea to seal it up in an air-tight container. Drugstore Beetles migrate to new materials quickly, so a complete inspection is critical. Don't forget to check the dry flower arrangements and any art work that has dried natural foods or plants.
Clean and Vacuum: Vacuum and clean shelves thoroughly. Pay attention to cracks and crevices and under your shelves, and around wire shelving.
Use Pheromone Traps: These traps have a sex pheromone in order to catch and trap male drugstore beetles. They will also attract male moths. Place only a couple of traps in the kitchen or pantry. We recommend the Invite Multi-Insect Lure. The Pantry Patrol Trap is not labeled for Drugstore Beetles.
Use Insecticide Aerosols: This is to be done after cleaning and before placing the foodstuffs back on the shelves. They will help prevent furture infestations in the cracks and crevices. For larger areas, use insecticide concentrations, such as D-Fense SC. Top recommended aerosols are Alpine PT or Phantom Aerosols.
