How to Get Rid of Boxwood Elders
- 1). Examine the window and door screens, noting any torn or missing screens. Replace these screens to prevent boxelders from entering your home.
- 2). Seal outdoor cable and wire outlets with caulk to limit the bugs' access. Fill in gaps that are 1/8 inch or larger. Seal up stone wall weep holes by using ventilation plugs.
- 3). Sweep up any indoors bugs you find, or use a vacuum cleaner to remove them. Do not use pesticides inside your home. Check any houseplants for boxelder infestations. Treat indoor plants by removing any visible bugs with your gloved fingers.
- 4). Spray infested outdoor plants and trees with a soap and water solution. Mix 1 teaspoon of liquid soap with 1 gallon of water in a pump sprayer. Soapy water will kill the bugs.
- 5). Spray the infected outdoor tree with an insecticide that contains bifenthrin, permethrin or tralomethrin. Follow the product mixing directions, or buy a product that is premixed.
