Note: Avoid placing ant bait too near the ant sprays application as spray will discourage ants from taking the bait.

When using the ant bait, don’t give up if ants do not go for it the first time – they may have found another food source or the colony could be in the breeding cycle hence not interested in eating. They could also be seeking a grease-based or sugar-based food other than protein-based. Switch the location of bait or switch the based of bait and try again.

Also, consider keeping a can of ant spray in the house at all times. They can be really handy when dealing with any sudden invasion by the little pesky pests. Ant sprays are also relatively cheap and can stay effective for a long time when stored properly.
