How to Get Rid of Black Ground Beetles

By Kimberly Sharpe ; Updated September 21, 2017
Black ground beetles are beneficial.

According to the Ohio State University Extension, more than 2,500 species of ground beetles live in North America. The beetles pose no danger to humans, pets, structures or plants. They will often frequent the inside of a house in their search for a warm winter hideaway in the fall. The beetles do not sting, but they can pinch with their mandibles. Ground beetles are beneficial to the ecological structure. They are a predator that feeds on numerous insect pests. Because of their great benefits and non-harmful status, ground beetles should not be killed using pesticides. Explore other avenues of control.

Caulk all windows, crevices and around any ventilation access holes, using exterior caulk and a caulking gun. Install screen over all windows and openings that lead under the house.

Pick up all yard debris around the house. Beetles enjoy residing under rocks, woodpiles, logs and leaves. Remove all areas that the beetles can hide under. Shake out welcome mats daily because many beetles will reside under the mats and then gain admission to the house when the door is open.

Paint the exterior of the home in darker colors. Beetles are attracted to light, bright whites or bright yellows and will often be drawn to a home that has light paint.

Place yellow light bulbs into all outside lights. Beetles are attracted to bright lights that are white and glaring. Yellow soft bulbs will attract less beetle activity at night. Pull your blinds and keep the doors closed at night so bright light does not shine outside to draw the beetles in.

Sweep ground beetles gently into a dustpan, using a broom, and quickly deposit them outside. A vacuum should not be used because it will often kill the beetles when they are sucked up.

 

Things You Will Need

  • Broom
  • Dustpan
  • Darker exterior paint
  • Exterior caulk
  • Caulk gun

Tip

  • Use pyrethrins or bendiocarb pesticides in the form of a spray or dust to kill beetles. This should be done as a last resort. Follow the directions on the label for application inside the home.

Warning

  • Some beetles emit a foul odor when handled. This is their defense mechanism and poses no danger to humans.
