Every year about this time, customers start bringing in photos of this strange white, fluffy substance on the stems of their shrubs and perennials. I myself have it on the stems of my Rose of Sharon. What on earth can it be? Well, it is not a fungus, as some have suggested. It looks fuzzy, so could it be a mealy bug? Nope. It is an evasive little insect called a leafhopper. I say evasive because if you’ve ever seen one on a stem, as soon as you get close [...]
Leaf-footed bugs are related to stink bugs. They can be distinguished from other types of stink bugs by the leaf-like appendages on their hind legs. Click HERE for more photos and information. If leaf-footed bugs invade your garden, learn what the eggs and nymphs (babies) look like. Oblong golden-brown eggs are laid in a string-like strand on the midribs of leaves or on the stems of the plant. Nymphs are orange or reddish brown and will develop the "leaf like" appendages on their hind legs as they mature. It is [...]
The Genista Caterpillar is the caterpillar commonly seen on the new growth of Texas Mountain Laurels. Note, it is ONLY the new growth that they will be found on. This saves us time and money in our control efforts. Any time Texas Mountain Laurels have new growth emerging, as in the spring and fall, is a good time to protect the new growth by spraying it with either Bt (Bacillis thurengiensis) or Spinosad. These are both Organic solutions to control caterpillars. [...]

We now have available to us a wide range of oil products to use as alternatives to synthetic insecticides and fungicides. These include oils distilled from petroleum and oils extracted from plants and animals. Petroleum oils (including mineral oils) are highly refined, paraffinic oils that are often referred to as horticultural spray, summer oil, spray oil or white mineral oil. We recommend Bonide “All Seasons Spray Oil” for late winter insect and disease control. (The antiquated term “dormant oil” referred to the heavier, less refined oils produced in the past [...]
Have you seen the Monarchs yet? Every year, I watch in expectation for the annual migration to pass through our area. I’ve been planting nectar plants all year in anticipation! Most of us have heard about the recent decline in the population of the Monarch, and how the use of herbicide-tolerant crops in the mid-west has limited the Monarch’s larval food plant, milkweed. We now have new information on how important the nectar plants are for the adult Monarch on the long migration to its Mexico breeding grounds in the [...]
Many of you are concerned about your lawns right now, as large brown areas are starting to show up as the summer heats up. I would encourage all of you to do an irrigation audit first, to determine if it is water-related. Never “assume” that all is being watered equally. Instructions for an easy, DIY irrigation audit can be found HERE. There are certain lawn issues that show up at specific times of the year, and there are specific times to treat them. For instance, we only see chinch bugs in [...]
Chinch Bugs Explained Here it is, the end of summer, and the hottest days are upon us. Many lawns have been showing signs of stress, and chinch bugs could be one of the culprits. Chinch bugs typically begin feeding in sunny areas along sidewalks and driveways, sucking juices from the grass blades and leaving yellowing grass bordering green grass. At the same time they are feeding, they inject a poison that causes the blades to turn brown and die. If your lawn is looking brown at the edges of [...]
All About Bagworms Bagworms have a fascinating life cycle! After hatching, each caterpillar spins a silk and leaf “bag” around itself. These bags are protective against predators, and are easily carried by the caterpillar as it crawls around feeding on trees and shrubs. If you see one of these little bags moving, look closely and you will see the head and front legs peeking out of the front of the bag. The caterpillars feed and grow throughout the summer, then pupate in August or September. The male emerges as a [...]
Giant wasps sound like something out of a nightmare! Fear not though, the huge yellow and black insects loudly buzzing around are gentle giants that are either slow to sting, or unable to sting, depending on the gender. Although they are Texas-sized, these wasps are not limited to our state, and can be found from Canada to Mexico. Cicada Killers, Sphecius speciosus (Drury), are large, solitary burrowing wasps. The name ‘solitary wasp’ may seem questionable as Cicada Killers can appear in large numbers, but refers to the fact that they do not [...]
There are many species of Lace bugs that can become abundant on certain host plants in certain years. (Do not confuse these with “LaceWINGS”, which are bright green, winged beneficial insects. Lacewing larvae eat aphids!) This year we have seen the destructive pest, Lacebug, on Texas Persimmon, Lantana and Elm trees. Watch for them on Azalea, Texas Sage, Pyracantha, Redbud, Bur Oak and Sycamore as well. Adult lace bugs are 1/8” to ¼” long and appear flattened. The wings are lace-like, and appear clear. Usually a [...]
It happens every year. Pecan tree leaves just are tasty to many different caterpillars, and it is inevitable that your trees will become dinner to one type of caterpillar or another at some time during the year. So, which one do you have, and how do you control them? Walnut Caterpillars and Yellownecked caterpillars usually appear in the summer and fall in Central Texas. There are at least two generations in Texas with the second usually being the largest in numbers. They are fairly large, up to an inch [...]
