The odorous house ant gets its name from the strong odor it gives off when it is crushed. The unpleasant aroma is likened to rotting coconuts. Odorous ant colonies can have up to 10,000 workers who forage for food in long, distinct trails. These long trails of ants are often seen indoors as they crawl over and contaminate various household surfaces. Outdoors the odorous house ant makes shallow soil nests under any material on the ground, within hollow trees, or in any other available cavity. Indoors they build their nests in wall voids, under insulation in crawl spaces, or within cavities in wood.

How Do Odorous House Ants Reproduce?

When a new colony is initiated, a queen lays a small batch of eggs and tends to the larvae that hatch. The adults that develop from these larvae go on to become workers and take over colony labor activities. During cold winter months, adults become inactive and larvae development slows. In spring, queens resume egg laying and colonies grow substantially during spring and summer. Odorous house ant colonies can produce hundreds of laying queens.

John arrived within the scheduled service window. He was very pleasant and did a great job. He double checked to see what issue I was having to ensure he put down the correct treatment type. He treated the inside, garage and outside perimeter of the house. In addition, he did a granule treatment on the shrubs per my request. John also took the time to explain how dampening the granules will activate them.?
