And now it’s mosquitoes

Hurricane Harvey continues to leave its mark on Texas. Besides the giant cleanup, hoards of mosquitoes are now descending in many areas. The pictures are impressive. Just a couple of examples are enough to make the point. The young man in the picture here was fortunate to have chosen a sturdy shirt before venturing out last weekend. The mosquitoes in this picture are probably in the genus Psorophora, (sore ROFF oh ruh) one of our largest, most painful and aggressive biters.  Psorophora mosquitoes have some impressive chops when it comes… Read More →

Fire ants make water rescue… interesting

What’s reddish-brown, rides the water like an air mattress, changes shape like an amoeba, and stings like the devil?  If you answered fire ants floating in floodwater, you’ve probably been in Texas high water before. Floods bring all sorts of wildlife into close and sometimes uncomfortable contact with people, but none perhaps so uncomfortable as fire ants. When their mounds are flooded, fires ants survive by riding air bubbles to the surface, joining feet (tarsi) with nest mates, and floating.  The ingenious behavior that allows ants to float… Read More →

A chance to fight malaria

How would you like to save a life today? It’s not as hard as you might think. In the years since Bill Gates retired his position as CEO of MicroSoft Corporation, he and his wife Melinda have devoted tremendous effort to battling malaria.  Malaria and the mosquitoes that transmit it is the single greatest killer of humans in the world, accounting for most of the 700,000+ mosquito-caused deaths annually.  But unlike many of the other major problems in the world, solutions to the malaria epidemic are available now….

Ticks and summertime

Everyone who agrees with this statement, raise your hands. “The world would be a better place without ticks!” Ha, just as I suspected! Everyone who has ever “gotten a tick” raised their hands. Everyone else has a blank look on their face. For the uninitiated, ticks are eight-legged arachnids more closely related to spiders than insects. While all tick species feed on blood, some feed on wild animals and rarely bite people.  Other ticks readily hitch rides on, and bite humans.  Ticks are most commonly encountered in fields or… Read More →

New infographic on biting and stinging pests

Every now and then we get the opportunity to get a little creative with a partner who shares some of our mission. This month our partner is the Methodist Health System, and MHS Publication Specialist, Sarah Cohen.  Sarah posed a challenge to a few of us subject matter experts, and her creative team, to come up with an infographic that would help inform you about the different kinds of pests in Texas that bite, sting and sometimes infect us. Here’s the final product and a link to the… Read More →

Bed bugs happen: Even in school

A message to all parents with kids in school:  Bed bugs happen. Bed bugs happen even in your children’s school, and like it or not we’re all going to have to deal with it. That will mean fighting the inclination to go into hyper-protective parent mode. Instead we all need to relax.  Deep breaths.  Eyes closed. Find your center.  Breeeathe… it will be all right. It doesn’t matter what kind of school our kids attend, there’s a good chance that sooner or later you’ll hear rumors of bed bugs on campus.  I… Read More →

Getting tested for Zika

So you and your significant other are considering whether to get pregnant; but the summer’s headlines about Zika virus and its effect on developing babies has you worried.  Or maybe you’ve just returned from traveling to an area where Zika is active.  You’ve not experienced symptoms of Zika, but you’ve been around others with the disease and you know that 4 out of 5 people who get Zika show no symptoms.  You wonder if you might be infectious to your spouse or partner (Zika can be sexually transmitted). In both cases a test… Read More →

New Zika publications

I was asked a few weeks ago if the collective “we” (meaning the whole state of Texas) were going to be ready for Zika.  My answer was a cautious, “I think so”.  If we’re not, it at least it won’t be for lack of trying. Zika is a much different disease than West Nile virus. It has different vectors, mosquitoes that prefer to feed on humans over any other animal (unlike WNV mosquitoes, which mostly feed on birds).  It is also very difficult to detect in wild mosquito populations.  The… Read More →

Quick fix for mosquitoes

This year my wife and I worked all spring to turn our backyard into a flowery paradise.  We installed drip irrigation, planted new plants (including a bunch of perennials for attracting bees and butterflies) and mulched everything against the coming drought of summer. Now that summer’s here, however, the mosquitoes have decided that since everything’s so nice, they want to be in charge.  In fact I believe every mosquito on the block knows about our backyard, making it difficult to go outside for even a few minutes without repellent. You… Read More →

First mosquito of the season

Before it’s old news, I wanted to make it official.  It’s Aedes (AID ees) season again in north Texas.  Last weekend I spotted my first Aedes albopictus (Asian tiger mosquitoes) of the season.  So from now until November, get used to having these pesky mosquitoes around. Alex Wild, curator of the insect museum at the University of Texas in Austin (the OTHER Texas University) tweeted his first Aedes aegypti (yellow fever mosquito) of the season a month ago.  Since then I’ve been tempting my local backyard mosquito population with my succulent, winter-white legs… Read More →
