An Overview On Ant Sprays

Indoor ant killers are not usually as potent as outdoor ant killers. This is because they typically have safety measures to keep humans and pets safe.

The most common types of indoor ant treatments are ant bait traps, powders and sprays. Sprays are the fastest and easiest to use, and they normally kill the ants on contact. Bait traps do not work on contact, and powders are made from Borax and have to be mixed with other ingredients.

Some sprays have repellents to keep the ants from coming back in the house; these create barriers. Non-repellent sprays allow the ants to walk through the spray and track it back to their colonies. This can poison the other ants, and that is a good thing. Other insect sprays contain toxic ingredients, so be extra careful to check for this before buying.

The Ant Spray Buying Guide

  • Try starting out with a non-toxic or organic ant spray first to see if this solves your infestation. It is always best to avoid chemicals and toxins where possible, and there are many more choices on the market than ever before.
  • There are some natural insect repellents, but they will not usually work for ant infestations. Commercially prepared products are your best bet if your ant problem is out of control.
  • Whatever you do, always read the instructions first before using insect sprays.
  • Wash your hands thoroughly after spraying and cleaning up.
