Out for Blood: The horse fly is a major pest – and a major pain to control

Published

There are few guarantees in life, but one guarantee is inescapable: if you have livestock, you have flies.
One of the best known of these pests is the largest, the bloodsucking horse fly. It is also one of the most difficult to manage, according to entomologist Dr. Sonja Swiger with the Texas A&M Research & Extension Center in Stephenville.
“Horse flies are hard to control,” she says. “They are only on the host long enough to take a blood meal and then they leave.”
When most people mention “horse fly” they think of the big black flies with huge eyes that look like rainbows on an oil slick when the light hits them just right. This horse fly is actually part of a large family, the Tabanidae, which includes both horse and deer flies, and like their distant cousins the mosquito, only the females are bloodsuckers.
A study by now retired Texas A&M entomologist Bart Drees and James Goodwin identified 109 distinct species of horse and deer flies in Texas alone, compared with about 350 species known in North America and 4,500 known worldwide. According to Dr. Swiger, some of these are very specific and localized, while others have evolved to take advantage of large herd animals; though, as many people have painfully learned, horse flies can be fairly opportunistic biters.

Land Market Report: January Land Sales

Published

The rural land market in North Texas has had a fairly stale start to the year, with the number of transactions closed being minimal so far. There has been an increase in call volume from buyers, and some are turning into contracts, but I feel like we are still a little slower than we usually are at this time of the year. The “experts” are expecting fewer transactions in 2024 as compared to 2023, and they may be correct, because election years always seem to be slower. Once the election is over, and regardless of who wins, things seem to pick up once again. It is a strange phenomena that just seems to happen every four years.

With the amount of growth that we are currently experiencing here, I do not expect things to get any cheaper. More people means more houses, and they have to have land to build those houses on.
