Best Ant Poisons

Terro Liquid Ant Baits are excellent poisons that work to kill not just the ant you have seen wandering around your kitchen, but the anthill they report back to. The stations contain a liquid bait that attracts the ants. The poison used in them is slow-acting, meaning the ants won’t die instantly.

The slow-acting poison allows the ants time to return to their colony and share the bait and its location with the rest of the members. Eventually, the poison will spread through the colony and to the queen, and your ant problem will be solved.

Terro’s liquid bait stations are very effective and extremely easy to use. The stations have a snap-off tab to create an opening where ants can get in. Once you have removed this tab, you simply need to place the station along the baseboard, near doors, or where ever else you have seen ants gathering.

Like their indoor product, Terro’s Outdoor Liquid Ant Baits work to effectively rid you of your ant problem, not just delay their intrusions. These pre-filled stations contain ant bait that attracts ant and slowly kills them with plenty of time for them to tell their colony mates.

What makes these stations different from the indoor versions is that they include a removable stake that can be used to push the stations into the ground, securing them. The stakes can keep them in place and prevent them from getting knocked or kicked over.

Secondly, the stations are weatherproof and are made to resist rain as well as UV rays from the sun. These features let the stations do their job undisturbed, making your life easier.

Since the bait station has a green design, users can place it in the grass for discrete ant elimination. They are very easy to use; users simply need to press down and twist a one-quarter turn. They work best when placed near entry points of your home and where you see the most ants gathering.

An ant problem is one thing, but a fire ant problem can have you in a panic. While household ants tend just to be pesky and annoying, fire ants can be painful and harmful. Fire ants can sting you, and those painful bites will soon turn to irritating, itchy bumps.

The Ortho Orthene Fire Ant Killer is a liquid poison that works by attacking the fire ants right at the source: the anthill. One bottle treats up to 54 mounds and is guaranteed to destroy the mound and kill the queen ant.

Individuals can use Ortho Orthene on lawns and to treat ornamental plants. It requires no watering and needs to be poured directly on the mound.

Terro’s Ant Killer Plus is a granular formula that kills more than just ants. This pest control is designed to attack and eliminate cockroaches, fleas, and other unwanted insects.

The granules are weather-resistant, so even after a rainfall, they can remain effective. They offer on-contact killing while providing long-lasting residual control, ridding you of your insect problem and keeping it that way long term.

These granules are meant for outdoor use only, but their uniquely-designed shaker bag allows for easy spreading. There is no need for you to touch the granules or purchase a spreader. Easy spreading makes this product good for perimeter control as well as contact killing.

The Terro Ant Killer Dust comes in a convenient and easy-to-use can. The can acts as a shaker, allowing you to sprinkle dust where needed easily. The dust is designed to kill ants on contact. However, the product is also designed to provide residual control for as long as eight months.

Ant killer dust can be used both indoors and outdoors. A waterproof product, this ant killer dust won’t wash away in the rain. It is highly effective on other insects as well, including fire ants, spiders, ticks, and wasps.

The fine dust texture of this product is ideal for cracks and crevices that other products can’t get into. Since it won’t wash away, the product will sit in these places for months to come, providing continuous protection.

Terro dust can be placed practically anywhere: porches, patios, garages, stairways, windows, and doors.

Optigard Gel Ant Bait is a powerful and highly attractive formula that targets ants as well as other harmful pests. This ingredient not only attracts ants, but it promotes the spreading of the gel’s active ingredient to the colony.

Good for both indoor and outdoor use, this gel targets and kills common household ants, carpenter ants, and ghost ants. As the ingredient spreads through the colony, more and more ants die, including the queen.

Since this gel comes in a small tube and is easily spreadable, users can spread it in small cracks and crevices where ants and other insects commonly enter the house.

An effective and affordable outdoor poison, the Terro Ant Killer Spray gives users the power of instant contact killing. It is capable of handling carpenter ants, carpenter bees, Asian lady beetles, and even cockroaches.

While the spray is powerful enough to product instant knockouts, it also works as a long-term control. This spray creates barriers that keep bugs out and away from your home. Just spray this formula around windows, doors, and foundations to keep insects from entering.

The aerosol spray reaches up to 10-15 feet. This feature is great for attacking from afar or getting to hard-to-reach spaces. The spray is most effective when ants are active, which is generally in the spring and the fall.

The Harris Borax Liquid Ant Killer is the best non-toxic poison because it uses borax, which is a naturally occurring mineral powder as its active ingredient. This ingredient and the product as a whole is EPA registered and approved, making it safe to use and good for the environment.

This liquid ant killer uses trays that hold the sweet liquid bait. The borax slowly kills the ants, leaving plenty of time for them to report back to their colony and spread the bait. More ants will begin arriving at the bait tray, and soon the whole colony will be affected and eliminated.

Harris’s liquid cleaner works best on sweet eating ants, sometimes referred to as sugar ants. That is why the liquid bait has a sweet flavor—it will attract more of these kinds of ants, which are commonly found in households.

To use, you pour the liquid formula into a tray and place it where you have seen the ants in your house. Bait will kill any single ant within 48 hours, but it can take up to two weeks to destroy the whole colony.
