Rainy Season Brings Out Desert Termites

Desert Termites Build Mud Sheets

If you found this muddy, stucco-like material on a post in your backyard, what would you think it was? And how was it created? The homeowner investigated by scraping off a sample and he found larva, tiny red ants and the trail seen in the second photo. If these were wooden poles one might guess the insects responsible were termites, but the gray poles are made of TREX, a man-made substance resistant to termites.

To answer this question, Dr. Carol SutherlandExtension Entomologist at NMSU and State Entomologist for the New Mexico Department of Agriculture, was contacted. She replied: 

“This suggests rain fell at their house. Desert termites (e.g. Gnathamitermes sp.) went into foraging mode. There’s probably landscape cloth around this post, but the termites found a little fold or tear that allowed them to reach the surface and check out what this big gray thing was. They made that brown ‘stucco’ out of the brown soil they were in, using their saliva to secure it periodically to the surface of something (TREX) that was of no use to them.

If you found whitish ‘larvae’ when the stucco was removed or fell off, those likely were worker termites. They avoid bright light, so they might have scurried back into the dark as the stucco was falling.  

The little red ants are likely Forelius—what I call ‘little sugar ants.’ They are the tiny creatures that treat your garden hose like I-25—3 lanes each going both directions with ants running full speed. Their usual food sources feature sweet-tasting things—like aphid honeydew. To find one of these food sources, they may explore their environment; in this case, it included the ‘termite stucco’ shelter vacated earlier by the termites. Subterranean termites usually have messy tunnels, which would account for some of the trails under the stucco being ‘highlighted.’ Any Forelius caught or squashed in those tunnels when the stucco was removed or fell would add to the reddish ‘dust’ that makes the old termite tunnels stand out.

The TREX formula makes cellulose unavailable to foraging or tunneling termites. In other words, TREX did what it was supposed to do.”

Desert termites are more likely to be seen from late spring to early fall and more so after rainy periods. They do not tunnel into wood but rather construct fragile mud sheets and tubes around the surfaces of plants, litter, fence posts and similar objects.

Mosquito-transmitted diseases are on our radar now more than ever. The bite of an infected mosquito can spread West Nile virus, chikungunya, dengue, and Zika. Texas A&M AgriLife Extension’s “Mosquito Safari” is an interactive audio-visual website that takes you around a house and neighborhood to learn where mosquitoes will breed so they can be eliminated. The website also discusses mosquito-borne diseases and how to control them. Read more »

Tiny Pests in Our Gardens

How can so much damage to our plants be caused by such tiny pests? Spider mites, aphids and thrips are sucking pests that we start to see on our plants when the weather warms. Be on the alert for these in your garden so that you can take measures to remove them before the damage is too severe. In the following articles from New Mexico State University (NMSU) by Carol A. Sutherland, the “IPM Notes” section will give advice on controlling these pests. Fortunately, a first line of attack can be a strong stream of water to wash them off the plant and clean off the dust that is favored by the spider mites. You can also learn more about “good bugs” and “bad bugs” in the July Gardening 101 talk by Texas Master Gardener Entomology Specialist, Mary Ann McCravey.
