What moves the price of termite control?
The price depends on the building and on how much of it has to be treated. The technician confirms it on site, and it is explained and approved before any work starts.
The main factors are the size and footprint of the building, whether it sits on a crawl space, piers or a slab, and how easily the sub-floor and the full perimeter can be reached. Outbuildings included in the job add to it, and so does a property that sits well out of town, where travel is a real part of the day.
Does a swarm mean my house is infested?
Not by itself. A swarm is how a colony disperses winged reproductives, and it does not on its own show that the building is infested.
Subterranean termite swarmers appear in the spring, and the sight of them near a window or a porch light is alarming for most people. Extension guidance describes eastern subterranean swarmers as generally flying in the daytime, which is one way to tell them apart from the night-flying insects that come to lights.
Why does a spot treatment often fail?
Because the colony lives underground and feeds from many points at once, so treating one damaged area reaches only a small part of it.
A colony of subterranean termites is spread through the soil, with feeding tunnels reaching into the wood at several places around a house. A treatment that touches the wood at one spot can kill the termites working there and leave the rest of the colony untouched. The colony then continues to feed, and the next damage often appears somewhere else.
What can a homeowner check before a technician arrives?
A few things, none of which is a diagnosis. They help the technician start from better information.
Walk the outside of the house and look at the foundation, the piers and the wood near the ground. Note where any mud tubes run, where the wings were found and when the swarm was seen.
