How to Treat Ants Under Liner of Swimming Pool

Swimming with ants is probably not your idea of a good time. If you have ants under your swimming pool liner, you likely want to get rid of them. Ants will often destroy the liner by chewing holes through it, sometimes creating so much damage it needs to be replaced. Unless treated, the ants can enter the pool, possibly causing harm to those inside, if the ants sting or bite. Fortunately, you can eliminate the presence of ants.

Ants in the pool can ruin a good time in a hurry.

Step 1

Spray insecticide around the base of the pool. Applying the insecticide right after pool installation will prevent the ants from ever getting under the liner at all. Placing bait around the pool is also a good idea, as ants will collect the substance and take it back to others in the nest.

Step 2

Place insecticide under the liner, if possible. If there are large holes in the liner that are big enough to place bait or a bottle of insecticide inside, spray the insecticide where the ants are located or drop a piece of bait in the hole. You may have to apply the product several times to eliminate the problem, but eventually the ants will die.

Step 3

Remove the liner from the pool, if the ants have created too much damage and have destroyed the liner. Before installing a new liner, treat areas under the liner with insecticide designed to kill ants.
