How to kill brown ants

Updated February 21, 2017

There are numerous types of ants that can invade the home and garden. The brown ants are often found inside the home and can be a health hazard and a nuisance. A few of the brown ant types are the odorous ant, Argentine ant, Caribbean crazy ant and pharoah ant. The actual type of ant doesn't really matter as most ant controls are broad spectrum. Ants live in nests or colonies and are attracted to most types of food. An untidy house or yard can make control difficult because the ants can't be found and have many hiding places.

Seal cracks in pipes, doors, walls and floors where ants may be gaining entry to the house. Remove piled up garbage and debris outside the home that may be providing nesting sites. Patch or seal holes where wires enter the house. Ants use any entry point to invade the home where foraging is easy.

Clean your house. Make sure crumbs and debris are cleaned from floors and counters. Ants are opportunists and will forage for these small scraps. Sanitise surfaces. Remove clutter that makes good hiding places. Make sure that dry goods are in sealed containers. Ants will invade a sugar bowl or other open food, so it is best to make certain these items are in closed canisters.

Set up bait stations. Bait stations are purchased with the insecticide inside the unit. They are safer for the home as children and pets can innocently pick up or eat exposed insecticidal poison. The unit is self-contained and the ants walk in, make contact with the poison and take it back to the nest. The rest of the colony will eat the bait and get infected.

Place sticky barriers in ant trails or places you have seen the most activity. The concept is simple. The ants walk onto the platform and are stuck in a thick glue-like substance. They will eventually die. When the traps are full, you just throw them away. It is a little unsavory to have plastic traps on your floor with ants in different levels of morbidity, but it is safe and non-toxic.

Call an exterminator. If the infestation is not responding to the previous attempts to kill the ants, it is time for professional help. There are insecticides and methods of application that are not available to the homeowner. The pests may live in a crawlspace or wall, which the owner is not able to access with their bait. Professional exterminators have the equipment to blow insecticides into those hard-to-reach places and have licenses for powerful poison controls.
