I have officially declared 2018 the year of the grease ant, or the cousin of the little black ant or a.k.a. the pavement ant. These ants, which usually make their homes under pavement, patio blocks and pavement stones, can also spend the entire year in your house. Yes, a year around nuisance. The colonies can be moderately large and by that I mean hundreds to thousands of ants. Swarmers (winged breeding ants that are around a ½” long) usually appear around June or July; nevertheless, I’ve seen them swarm in just about every month inside a home. When they are discovered indoors they can be found in walls, under floors, and in insulation. If your home is a slab-on-grade construction, with radiant floors or forced air, they usually get in through cracks or expansion joints in slabs. Most notably, their nests can be located behind baseboards, in wall cavities, near plumbing, sinks, toilets, and along the edges of carpets. The use of retail purchased insecticides, dusts and those round bait pucks stress ant colonies, triggering them to split into sub-colonies and scatter. This scattering, known as budding, increases the number of ant colonies, and thereby swells your ant problem. Once you have given up trying to contain these beasts, look us up at go green pest control.ca and we will be happy to irradiate them. Oh, and yes they do bite and sting.
