Frequently Asked Questions

  • Are these the same as Pavement Ants?No. Little Black Ants are significantly smaller than Pavement Ants and are more likely to nest inside wall voids rather than under the driveway.
  • How do they get into sealed containers?Because they are so tiny, "sealed" is a relative term. They can squeeze through the threads of a screw-top jar or the folds of a cereal bag with ease.
