Location of Infestation: Determine whether the infestation is indoors, outdoors, or both. Some ant killers are specifically designed for indoor use and are safe around pets and children, while others are formulated for outdoor use to cover larger areas.
Active Ingredients: Check the active ingredients. Some products contain natural ingredients that are safer for use around the home, whereas others might contain stronger chemicals that require caution during application.
Form of Ant Killer: Ant killers come in various forms, including baits, gels, sprays, and granules. Baits and gels are effective for killing entire colonies by allowing ants to carry the poison back to the nest, while sprays and granules might offer immediate results and are suitable for treating larger areas.
Safety: Consider the safety of the product, especially if you have children or pets. Look for products with child-resistant packaging and those labeled as safe for use around pets and wildlife.

Effectiveness and Speed of Action: Review the product's effectiveness and how quickly it works. Some ant killers start working immediately, while others might take a few days to show results but offer longer-lasting protection.
Longevity: Consider how long the product will continue to work after application. Some ant killers provide protection for a few weeks, while others can last for several months.
