Does borax kill carpenter ants?

Ehrlich Answers

"Does using borax to kill carpenter ants really work?"

Borax for carpenter ants works as a bait when the substance is mixed with sugar and foraging ants take a small amount of sweet liquid bait back to their colony. Borax is toxic to ants and the mineral slowly affects their digestive system, eventually killing them. It can help reduce ant activity, but it might not solve the problem on its own. 

Carpenter ants often build satellite colonies, so whilst they may initially take some of the mixture back to one colony, their main colony may be located outside or nearby so it’s unlikely to be an effective solution for fully getting rid of an infestation.

How long does it take borax to kill ants?

There’s no single timeline, since colony size, food preferences, and nest location all play a part. Keeping the bait moist helps because ants prefer liquids and syrups; when borax and sugar mix dries out and crystallizes, carpenter ants are less likely to feed on it. If you’re using borax to kill carpenter ants, refresh small amounts often and be sure to place it where children and pets can’t access it.

It’s also important to get the mix of water, sugar, and borax right. A strong solution can kill a few foragers before they share it, while a very weak one won’t do much or may mean the ants are not attracted to it at all.

Using borax can work in the short term, but to protect your home and get to the source, rely on professional carpenter ant exterminators from our ant control services. We can inspect, find nests, and build a targeted plan that can not only eliminate infestations but also help prevent them from returning.
