Finding winged termites is a red flag
Q: Can I bring in some insects for you to determine if I have termites in my house? B. W. Whitestown
A: Spring is the prime time of the year when Boone County residents bring me samples of bugs in jars, wondering if they are termites, or if they are ants. Both ants and termites have wings at certain points in their lives. In most cases, the samples in question are ants, but sometimes I have to break the unpopular news that they are indeed, termites.
Finding winged termites in a home or other building is a near-certain sign that the structure is infested, according to Tim Gibb, Purdue entomologist. Normally termites stay hidden, either underground, inside wood or in mud tubes in order to maintain the humidity that they need to survive. It is only when the winged reproductive forms are produced that they become plainly visible, and this only happens sporadically.
Winged termites are about 1/4 to 3/8 inch in length and vary from black to yellow-brown in body color. They have four equal-sized, smoke-gray to brown wings that extend past the length of their body. Winged termites are also known as “swarmers” because they come out in large numbers all at one time — usually during the springtime, and after rain.
Many people confuse winged termites with winged ants. It is very important to know the difference between swarmer ants and termites. Winged termites have a thick waist, straight, bead-like antennae, and a pair of long, equal-length wings. Winged ants have a constricted waist, distinctively elbowed antennae, forewings that are larger than the rear wings (unequal size). The narrow waist (ants) versus broad waist (termites) is, in my opinion, the easiest way to tell the difference between an ant and a termite.
Swarmer termites also keep their wings attached only for a short period of time. After that, the wings break at their base and are discarded, sometimes in large piles. The presence of winged termites, or their shed wings, inside a home should be a warning of a termite infestation.
Ants can be a nuisance, but termites can be down-right destructive. They must be controlled in order to save the home, according to Gibb.

Can I Remove Daffodil Foliage Now?
Q: Now that the daffodils have bloomed, can I remove the foliage without harming them? C. T. Zionsville
A: Cutting off daffodil foliage before it has died back naturally, may prevent the plants from storing adequate food in the bulbs. The best advice is to allow the daffodil foliage to die completely before removing it. A rule of thumb is that it should remain for at least six weeks after the daffodils have bloomed. If the unsightliness is a problem, you can likely get a jump of a few days by removing it as soon as the foliage starts yellowing. But, that won’t occur until well into the month of June.

My blending project
When I got divorced, I was certain that I would never get married again. Not only was I not interested in putting up with another man, but the divorce rate for second marriages is even higher than the rate for first marriages.

On one side of the stair rail, two chubby legs kicked up and down as if in a swimming pool. On the other side, a tear-stained, reddened face howled for help.

In my newsletter I try to touch on the subject of sulfite every few years because this seems to happen on a pretty regular basis. The latest visit was from the couple who were just back from Europe.

Untangling the Kudzu for a new school year
While walking the dogs on a country road the other day, I noticed a for sale sign on a lot hidden behind an overgrowth of vines and brush. The vague imprint of tire tracks nearby reminded me a house was visible on the lot a few short months ago. Gray, dilapidated and abandoned, nature totally disguised the house from sight after just one summer of neglect.

The favor of a reply is requested
My best friend from high school used a rubber stamp and ink to stamp a message on the envelope of every letter he would mail (this was way before e-mail came about). The message said, “The favor of a reply is requested,” and it appeared just below a picture of an animal — I think it was a penguin.
