How to treat your crapemyrtle for bark scale

YouTube is both a tremendous waste of time and also one of the best things to happen to DIYers in, like,… forever.  I find myself checking it constantly for instructions on how to do everything, from troubleshooting my computer to making repairs on my car.  So why not a video on how to control crapemyrtle bark scale? What is crapemyrtle bark scale (CMBS)? It’s a small sap-feeding insect that lives on the bark of certain plants, especially crapemyrtle. Thanks to its sugary excrement, it turns crapemyrtles with beautiful… Read More →

Emerald ash borer makes a move

Ever since the dreaded emerald ash borer (EAB) showed up in Arkansas and Louisiana, tree lovers have braced themselves for its inevitable arrival in Texas.  Then, in May 2016, the insect was discovered in a single surveillance trap near Caddo Lake in Harrison County in east Texas.  In 2017 all was quiet, with no officially reported sightings; but this summer the beetle has been found in possibly three new counties. What is EAB? The EAB is a small but powerful beetle pest–an enemy of ash trees. Adult beetles… Read More →

Insect ID via mobile device

I get lots of images in email and on the web for identification. I get to see some amazing insects and good pictures this way, but I also receive a lot of really bad insect pictures. And since bad pictures don’t help your chances of getting a successful identification, it’s in everyone’s interest to take better pictures.  So here are five tips for improving your chances to get an insect identified via email, your cell phone or other mobile device. Focus on the insect, not the background.  Corollary… Read More →

Chigger season

If my phone calls are any indication, this appears to be a whopping chigger season.  Don’t know what I’m talking about?  You should count your blessings. Chiggers are my personal worst nightmare. They are tiny mites, barely visible to the eye, that live on the soil surface and, in their larval stage, are parasites on humans and other vertebrate animals. Chigger bites itch terribly for 1-2 days, then slowly shrink to mildly itchy red marks that take 1 or 2 weeks to disappear. The only good thing I… Read More →

Oak catkin mirid

Naturalists in Texas have no shortage of interesting insects to observe. If you were paying attention over the past couple of weeks, you may have noticed a small bug present in large numbers, especially around live oak trees. I’ve received several samples, some of which were sent by curious homeowners and some by pest control professionals. In some cases, they were observed clustering around doorways, other submitters just remarked that they were “very common right now.” Given the large number of small brown plant bugs on Bugguide, I… Read More →

When is Sevin not Sevin?

Any gardener who’s been around the block a few times has probably used the insecticide Sevin®, known generically as carbaryl. First introduced to the public in 1956, carbaryl was the first commercially successful product in the carbamate insecticide class.  Since then, it has been a pest control workhorse for vegetable gardeners and fruit growers.  It’s relatively low cost, broad spectrum activity, and relatively short (usually 3-day) interval between application and harvest made carbaryl a popular choice for growers.  Its relatively low oral and skin toxicity to mammals also made… Read More →

Bug bombs away

For many of us, the ultimate solution for cockroaches and bed bugs and other household pests is the “bug bomb.” Remember the old Raid commercials, where bugs flee from Mr. Raid, only to be followed home by the ominous cloud of death?  The implication is that the cloud from a bug bomb is like a heat seeking missile, able to follow pests into their deepest safe houses. So how well do bug bombs really work?  It turns out, not nearly as well as the animated ads suggest. Give… Read More →

Give the love of insects this Christmas

Parents, here’s a Christmas idea for your kids. A hand lens, an insect net, a set of pins and an insect collection box could provide a doorway to the love of nature for your child. For some kids an insect collection can be the best way to learn about insects and connect with the outdoors. Photography is also good, but collecting engages all the senses in ways that a camera cannot. Many entomologists got their start collecting insects. An insect collecting kit as a Christmas present got one… Read More →

2nd Edition of Garden Insects of North America

The Master Gardeners I have trained over the years may remember the big stacks of books I bring with me to every insect class.  I love books and use them a lot in my job. One of the most useful references I use and recommend to Extension volunteers is the Princeton University Press Garden Insects of North America.  It’s been a great resource, and a bargain to boot, since it came out in 2004. Now Garden Insects of North America has a second edition.  The original author, Whitney Cranshaw… Read More →

Devastation of Monarch butterfly habitat in 2016

For all fans of monarch butterflies, a new article in American Entomologist may be of interest.  Lincoln Brower and colleagues describe the most devastating weather event for the monarchs since studies began 24 years ago. For many years it was known that monarch butterflies migrated; but not until 1975 did scientists discover that most monarchs in the eastern half of the United States migrate to a remote mountainous site in south-central Mexico. The Monarch Butterfly Biosphere Reserve was designated a World Heritage Site in 2008, and is located… Read More →
