How to Get Rid of Boxwood Elders

Boxwood elders are also known as boxelder or box elder bugs, but their official classification is Boisea trivittatus. These non-biting insects pose a problem to homeowners because they travel in large groups, perhaps nesting indoors and excreting a staining hormone when excited. Boxelder bugs reach 1/2 inch in length, and mature bugs can fly. Boxelders like invading houseplants but don't do much leaf or root damage. If you've discovered these six-legged bugs in your home or yard, there are protective measures you can take to deter future visits.

Window and door screens
Exterior silicone caulk
Broom or vacuum cleaner
Liquid dish detergent
Pump spray
Insecticide

Instructions

- 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.
