Your Ant Killer Buying Guide

If you have a problem with ants and want to resort to using pest control, our guide will help you to choose the best one for your home and situation.

Ant killers come in different forms, each perfect for a particular kind of ant problem. Granules, ant baits and ant killer gel are ideal for eliminating nests and colonies. Granules, ant baits and gels are also very convenient, requiring you just to apply and get on with your business. But, if you wish to enforce a more hands-on solution, liquid insecticides and aerosol can spray is the answer.

The Target

Not all ants can be eliminated in the same way as some are harder than others. While common ants and meadow ants can be easily controlled with most of the products on the market, fire ants are much more difficult to control. If your target is a colony of fire ants, go for a product made explicitly for fire ant solutions.
