Elimination

Since ground beetles do not develop indoors, there is no point applying pesticides everywhere in the house. If you frequently see ground beetles in the home, it is because they are coming in from outside. It is best to relocate them outside or apply Maheu&Maheu Crawling Insect Killer locally inside. You can also put a Maheu&Maheu Universal GlueTrap along a strategic wall. The sticky trap is an ecological alternative to pesticides.

If the problem persists, it is strongly recommended that you inspect the foundation and nearby structures to determine how they are getting into the house and then caulk the hole.

Actions

  • Take insects outside as they are beneficial predators
  • Spray or treat the outside perimeter of the house with an insecticide if a lot of insects are getting in
  • Use glue traps indoors to capture individuals that get in

Prevention

  • Remove fall leaves and other organic matter around foundations as well as objects insects could hide Under
  • Seal the outsides of windows, doors, eaves, chimneys, etc. as completely as possible

Description and development

Ground beetles belong to the Carabidae family, one of the biggest families of beetles. There are over 450 species in Quebec alone. Ground beetles generally have shiny black bodies, but some are very colorful. Their elytra (hard pair of wings typical of beetles) may or may not be striated. Their size can vary considerably, from 2 mm to 35 mm in length, depending on the species. Ground beetles lay their eggs in the soil. The larvae, like the adults, are predators, which hunt ground-dwelling insects, worms, and slugs. They often hide in dense vegetation, under rocks, and in soil litter or woody debris.

Habits

As already mentioned, ground beetles are predatory insects, and many species are very useful. Some can emit an unpleasant odor when disturbed. They are generally active at night, but are often attracted to light. It is generally the adults that infiltrate houses.
