Swarms
With some warmer weather comes the swarms of insects that raise that perennial question of "Are they ants or termites?" Swarming time for both insects is about the same time, and they are really looking to start new colonies because they have outgrown their old ones. This is the reason for the winged insects, as the wings allow the ants or termites to cover larger areas to start their new colonies. The differences between ants and termites are several.
Let's start with the body color. Termites are always blackish in color, while ants may be black, red, brown, or other colors. If you have winged insects that are not black, you don't have termites.
Next look at the body shape. Ants have a constricted "waist" while termites don't have that classic "hour-glass" figure. Antennae and wings are the other two body parts to look at. Antennae on ants are elbowed, basically in an "L" shape, and those on termites are straight. Both ants and termites have two pair of wings, but those on termites will be of equal length while ants will have wings of different lengths on each side.
Looking through those entomology fact sheets also brings up a few important points in the event that you do have termites. First, don't assume that the house will fall in overnight. Take the time to get several bids from reputable companies for the treatment. Make sure you compare cost, service, and guarantees. Second, termites are pretty much a professional treatment job, unless you have an exposed foundation such as in a new construction project. Third, there are traditional treatments to kill the insects, and other treatments which render them incapable of reproducing. Drenches, pressure injection, and bait stations are all options. If ants are your problem, use of bait stations or baseboard sprays may help solve your problems. Many of the bait station programs will require a good week to ten days to be effective. Remember that damage done by ants, even carpenter ants, is not structurally damaging to your home. They simply make a nesting hole in wood rather than digest it.
If you have further questions on termites, or the do-it-yourself identification doesn't seem to work, by all means contact the Extension Office at 732-8289.
