The first step is to correctly identify the insect because pharaoh ants are often confused with other species. Once you're sure you’re dealing with pharaoh ants, we strongly recommend calling in a pest management specialist. By their nature, pharaoh ant infestations can be a tough challenge. Residual contact insecticides are not recommended because a colony may split up on contact with the product, and the infestation may spread to multiple rooms. Bait with insecticide should be the first step. But off-the-shelf ant baits may not be effective because they aren’t developed specifically for pharaoh ants. Your best weapon in ridding your home of these pests? Patience!
