Ants, with their organized colonies and scavenging abilities, are fascinating creatures to observe. However, when they start creeping into your home or garden, they can become a nuisance. Not to mention, some ant species can actually damage your property or even cause harm to you or your pets. In this blog post, we'll explore the best outdoor ant killer options to safely and effectively eliminate these pesky invaders.

Diatomaceous Earth

Diatomaceous earth, also known as DE or fossil shell flour, is a natural and affordable solution to ant infestations. This white powder is composed of microscopic fossilized remains of diatoms, a type of algae. When ants come into contact with it, the abrasive nature of DE damages their outer shell, dehydrating and killing them. Simply apply the powder to ant trails, nests, and crevices around your home and garden. The only downside is that it can be messy and may need to be reapplied after rainfall.


Borax is a common household item that can double as an ant killer. It works by interfering with their digestive system, causing them to starve to death. Mix 1 tablespoon of borax, 1 tablespoon of sugar, and a few drops of water to create a paste. Place the mixture on small pieces of paper near ant trails or nests. The sugary scent will attract the ants, and the borax will do the rest. Be sure to keep the mixture away from children and pets, and only apply it in areas where ants are present.

Ant Bait Stations

Ant bait stations are another effective option for outdoor ant control. These pre-filled plastic containers contain a slow-acting insecticide mixed with sweet liquid bait to attract ants. The ants bring the bait back to their nest, where it will spread throughout the colony and eventually kill them all. The bait station design also keeps the insecticide contained and away from children and pets. Place the stations around your yard, near ant trails and nests, and replace them every few months.

Contact Insecticides

Contact insecticides are chemical sprays or powders that kill ants on contact. They're a quick and easy solution for smaller ant problems, but may not be the best choice for large-scale infestations. Be sure to carefully read and follow all product instructions, wear protective gear, and keep children and pets away from treated areas. Always choose a pesticide that's labeled for use against ants and labeled for outdoor use.

Essential Oils

For those who prefer natural solutions, essential oils can provide a fragrant and effective ant-repellent. Ants are sensitive to certain scents, so peppermint, cinnamon, citrus, and tea tree oils can be a great deterrent. Simply mix a few drops of your chosen oil with water in a spray bottle and liberally spray ant trails, entryways, and other ant-prone areas. To avoid harming beneficial insects like bees and butterflies, spray in the early morning or late evening when they are least active.
