Odorous house ants are an annoying pest, which you can differentiate from other types of ants because the rotten coconut scent they emit when they are crushed. They are between 2.4mm and 3.25mm long, with a black or brown one-node body, and 12 segmented antennae, but their distinct odor is the easiest way to identify them. Like other ants, they are attracted to food and water sources in the home. Because their preferred food is sweets, they often go inside when their natural sources of food is threatened. Rainy weather and the autumn leaf fall are two events that threaten their food supply and can drive odorous house ants inside. They can forage around-the-clock, which, fortunately, can make them easier to spot than other types of pests. They may also nest in your home; they like to make their homes in wall voids, such as the areas around pipes or heaters. They can also nest outside in soil.
Once you identify that you have an odorous ant problem, you will want to eliminate them. They leave a pheromone trail for other ants, which leads from the nesting site to food sources. These trails mean that a minor ant problem is likely to rapidly increase. However, if you can locate and identify these trails, they also give you a clue on how to eliminate the ants. Baiting is an effective way to control odorous house ants, and you want to bait on the trails after eliminating other food sources. Different baits work in different ways, so for DIY odorous house ant control you want to choose a combination of sugar-based and protein-based baits. You also want to make sure and use slow-acting baits, so you can kill the queen.
