Discovering winged termites indoors whether subterranean or drywood almost perpetually indicates an infestation warranting treatment. Folks usually confuse winged subterranean termites with ants, which often swarm at the identical time of year. Termites can be differentiated by their straight antennae, uniform waist and wings of equal size. (Ants have elbowed antennae, constricted waists and fore wings that are longer than the hind wings.)
The swarmers are interested in light and are often seen around windows and doors. Termite swarmers emerging from tree stumps, woodpiles, and other locations out within the yard don’t seem to be essentially caused for concern and don’t essentially mean that the home is infested. On the opposite hand, if winged termites are seen rising from the bottom of a foundation wall or adjoining porches and patios, there’s a good chance the home is infested conjointly and treatment could be warranted.
They Look Different
Alternative signs of infestation for subterranean termites are earthen (mud) tubes (shown right) extending over foundation walls, support piers, sill plates, floor joists, etc. The mud tubes are sometimes concerning the diameter of a pencil, but sometimes can be thicker.
Termites construct these tubes for shelter as they travel between their underground colonies and also the structure. To facilitate verify if an infestation is active, the tubes might be broken open and checked for the presence of little, creamy-white employee termites.
If a tube happens to be vacant, it will not essentially mean that the infestation is inactive; termites usually abandon sections of tube while foraging elsewhere within the structure.
Termite-broken wood is usually hollowed out along the grain, with bits of dried mud or soil lining the feeding galleries. Wood damaged by moisture or alternative varieties of insects (e.g., carpenter ants) can not have this appearance. Occasionally termites bore tiny holes through plaster or drywall, in the course of bits of soil around the margin. Rippled or sunken traces behind wall coverings will additionally be indicative of termites tunneling underneath.
Oftentimes there can be no visible indication that the house is infested. Termites are cryptic creatures and infestations can go undetected for years, hidden behind walls, floor coverings, insulation, and alternative obstructions. Termite feeding and injury can even progress undetected in wood that is exposed as a result of the outer surface is typically left intact.
Confirmation of infestation often needs the keen eye of an experienced termite inspector. But, even the most experienced inspector can overlook infestation or harm that is hidden.
