Learn how to prevent and deal with ant infestations.

Prevention

Ants typically come indoors looking for food, water, or shelter.

  • Find out how to prevent an infestation.
  • If you have an infestation, use the tips below to get rid of the ants.

Indoor infestation

If ants are indoors:

  1. Clean the infested area with soapy water or ammonia window cleaner.
  2. Eliminate ant food and water sources.
  3. Use a pesticide-free spray to discourage invasions.
  4. Seal entry points with petroleum jelly or duct tape until silicon caulk can be applied.

If the problem persists, request assistance. Eradicating the outdoor colony is the only way to eliminate recurring infestations.
