FAQs

We have provided you with some of the best ant sprays in the business, and now we would like to equip you with knowledge as well. Read on to learn the answers to some commonly asked questions concerning ants and ant spray.

What is the difference between ant bait and ant sprays?

Ant sprays are best for on-the-spot ant elimination and prevention. Ant spray can be used to kill the ants that you see in your kitchen, and some can be used to create barriers around a certain area. While killing on the spot is very useful, this product can prevent ants from entering your house altogether.

Ant bait is good for bigger ant problems. You can use ant bait to attract a colony of ants and kill them all after an infestation takes root. While ant spray kills and repels ants, the bait
will attract them and poison them.

What active ingredients help to eliminate ants?

The active ingredients in your ant eliminators depend largely on the company and their unique formula. Many ant baits use Boric Acid and other Borates. These ingredients are naturally derived ingredients. Companies sometimes use methoprene and pyriproxyfen. They are insect growth regulators that stall the ants’ development, killing them.
Some other common ingredients you may find in baits are hydramethylon, neonicotinoids, and avermectin.

Ant sprays tend to use different active ingredients than bait, as they are meant to kill on contact rather than slowly. Sprays often use botanicals, which are naturally occurring substances that can include thyme oil, hot pepper extract, limonene, clove oil, and linalool.

Do I need different kinds of sprays for different kinds of ants?

Many ant sprays use various chemicals that work to kill the ants. It can be hard to know if one works better than another.

For this reason, companies will often make sprays that specifically target harder-to-kill ants. For example, our best ant spray for carpenter ants will most likely do a better job of killing carpenter ants than a non-specific ant spray will do.

For small, general household ant problems, you don’t need to worry too much about looking into specific ant sprays. The sprays from the list above should do the job. However, bigger issues may require additional tools such as bait or exterminators.

How do I know when it’s time to switch to long-term ant killer?

Ant sprays are great short-term solutions to small ant problems. For example, you see a few ants on your counter, but there doesn’t seem to be a trail or a larger group somewhere in your house. An ant spray will do the trick to kill those worker ants, and your problem is solved.

The problem arises when you start to see ants every day, and no matter how many times you spray them, more come back. Soon you may start to see their numbers grow, or you may notice trails of them coming from a crack in the wall or a crevice near your back door.

At this point, you may have a larger problem at hand.

If you weren’t able to catch the small problem while it was still small, you might have to heighten your efforts. One thing you can try is switching from a spray to bait. Bait will attract more ants at first, but you have to let that happen in order to kill the rest of the colony.
