Identify the species of ant infesting your home and match your bait to the type of ant.
Offer a small quantity of a grease-based bait, a protein-based bait and a sweet-based bait if you are in doubt about the species of ant. Monitor the ants to see which bait is most readily accepted.
Follow a trail of ants to their exit point from the room or house. Place bait stations at or as close as possible to these points.
Avoid use of insecticide sprays on or near ants while using bait. If foraging ants are killed before they return to the colony, your bait will be ineffective.
Keep counters, crevices alongside sinks and hobs, skirting boards and floors clean and free of food particles. Your bait must be the only food available to the ants.
Maintain a good supply of fresh bait. Rancid or dried-up bait is unattractive to ants. Ensure that bait does not get wet or contaminated by other substances as this will deter ants from eating.
Things You Will Need
- Appropriate bait for species of ant
- Baiting can take up to several weeks to be effective.
- You may need to use more than one dose of bait to eradicate a large colony.
- Check that your bait does not contain cyfluthrin or permethrin, as these are actually insecticides, which will kill the ants before they return to the colony.
- Check labels on bait containers to see what active ingredients they contain and to read guidelines for use.
