Termites
If you think you have subterranean termites, then you need to be positively
certain. Subterranean termite swarmers appear in the United States
starting in February (south Florida) and swarm until early June
for the northern areas of the United States. In most instances of
swarming, the individual termite colony only swarms 1 or 2 times.
It is not a constant swarming cycle, and unless you are lucky
enough to witness the swarm or find dead swarmers or wings, you
may miss it. You may normally find workers, soldiers and/or swarmers, but
you will not find queens or kings because they are hidden deep inside their colony.
If you do not see signs of swarming, then there are other signs that you can look for.
In coastal areas of the US, drywood termites are
common. Drywood termite swarmers differ from
subterranean termites in color. Drywood termite swarmers are
red with blackish wings - and can be confused with Florida
carpenter ants.
The most obvious sign of subterranean termite infestation is mud
tunneling. Subterranean termites build mud shelter tubes in which
they travel. These mud shelter tubes are connected with the
termite colony, and are constructed of dirt and an acid substance
that the worker termites secrete. The mud shelter tube helps to
protect the worker termites from predators such as ants, and also
provides them with humidity. Most importantly, mud shelter tubes
give the blind worker and soldier termites a highway in which to
travel to and from their food sources. Mud shelter tubes are very
hard packed, and usually as they get older, they get harder and
larger. Some mud shelter tubes are as small as a pen; others can
be several inches wide.
Mud shelter tubes are usually seen on the outer sides of foundation
walls as seen in the photo above. They can also be seen emerging
from sheetrock in ceilings, and on sheetrock walls as shown in
the pictures below.
