A Changing Landscape in Subterranean Termite Control

This is a summary of a recent presentation by Dr. Thomas Chouvenc on the importance of termite colony biology on control methods

Termites evolved from cockroaches 150 million years ago. There are now over 3,000 termite species worldwide, yet only 3 percent of the overall diversity are pests. They have extremely important roles in subtropical and tropical ecosystems, decomposing wood and other forest litter, and returning those essential nutrients and carbon stored within the dead wood back into the cycle for soil enrichment. That alone is a worthy designation. However, for all the amazing benefits termites provide in the natural environment, there is a zero-tolerance policy once they enter our homes. A mature Formosan subterranean termite colony can consume about 300 pounds of wood per year.

Current Situation

In Florida, we have the highest diversity of termites in the United States. There are 21 different species of termites in Florida, and two of the most damaging termite pests occur in south Florida, Formosan subterranean termites, Coptotermes formosanus, and Asian subterranean termites, Coptotermes gestroi. Within six months of an infestation, structural damage of a home can occur because of the sheer size of the colony. Subterranean termites have large underground colonies, often in the millions, with a central nest where the king and queen reproduce and brood are maintained by young termites. Termite workers go out and forage for new food sources, often very far, up to 300 feet, from the central nest, through an underground tunnel system. They need to maintain a moist environment and cannot survive without water. Subterranean termites attack wood that contacts the soil and build mud tubes or tunnels, to maintain moisture, and reach wood in structures and trees away from the soil surface. So, if a subterranean infestation is discovered in a home, it is only a small portion of the entire colony, which is why we do not fumigate for such subterranean species. Structural fumigation is used against drywood termites, which colonies often infest a single piece of wood.

What has recently been discovered, is these invasive subterranean termites are also killing living, healthy trees in the urban south Florida environment. In most cases, the termites feed on the wood or old xylum tissue deep within the tree, not on the live vascular tissue, so the tree appears to be healthy until it collapses on its own weight or when a tropical storm or hurricane passes. One of the ways to detect the early presence of invasive subterranean termites is to regularly inspect trees surrounding structure and look for termite activity, often noticeable by the presence of mud tubs on the bark or at pruning wounds. Knowing if these species are established in your area is also an important, as it tells if you are in an area at risk of infestation. The current distribution map of termite pest species is accessible at https://flrec.ifas.ufl.edu/termites-in-florida/termite-distribution/.

Termite Biology

Termites are eusocial insects, like ants and bees, that live in massive colonies with cooperative care of the young, overlapping generations, and a reproductive division of labor, meaning only a few members of the colony reproduce (king and queen). However, they differ from ants and bees, in that they are hemimetabolous, which means the immature insects looks like miniature versions of the adults and do not have go through metamorphosis. So, termite workers, which are sterile, will continue to molt throughout out their life until they die. Interestingly, they do not molt at the foraging sites due to lack of care and protection in these environments and return to the central nest to be cared for by nurse termites (young workers) during the molting process. This has become a very important aspect in understanding their biology and adapting control practices based on new technologies.

Control

Traditional subterranean termite control involves the use of liquid termiticides and still represents a significant portion of all subterranean termite treatments in the United States. The goal of these treatments is exclusion from the home through a chemical, insecticidal barrier around the structure, killing organisms that encounter the barrier before they enter the home. These products are mostly non-repellent, meaning they are undetected by the termites, and are broad-spectrum insecticides, so they are not only going to kill termites on contact, they will kill any insects that come into contact with the treatment area. Additionally, most liquid termiticides are non-persistent and break down in the environment within a few years. In recent years, more and more pest control operators have been reporting failures with liquid termiticide treatments of Asian subterranean termites according to Dr. Thomas Chouvenc, as cumulative evidence suggests that such subterranean termites may eventually find a way to bypass the treatment through strong foraging pressures.

Newer technology involves the use of Chitin Synthesis Inhibitor (CSI) Baits placed around the structure or home. The goal with CSI baits is colony elimination. Chitin Synthesis Inhibitors work by preventing the formation of chitin which is needed to form an insect’s exoskeleton. So, the insects grow normally until it is time to molt, and the inhibitors prevent the new exoskeleton from forming properly and the insect dies, usually around 40 days after ingestion. These insecticides are targeted for consumption by termites only and a minute amount of pesticide is used in comparison to liquid termiticides. So, termite workers forage and feed on treated wood baits, return to the main nest, and share the food (carrying the active ingredient) with the brood and the rest of the colony through trophallaxis (a food exchange process common in social insects). Colony elimination is usually achieved within 90 days after the initial feeding on the bait.

A study by Dr. Nan Yao Su in 2005 looked at distance as a parameter for understanding termite control. In a laboratory experiment with about 10,000 foraging termites and 150 feet of tubing used as the foraging system, Dr. Su found termites within 10 to 15 feet of a commonly used liquid termiticide treatment died within one week. However, beyond that, the colony was not affected, and the remaining termites closed the tunnel system to separate themselves from the area with termite mortality. So, what is happening, according to Dr. Su, is secondary repellency in the treated area due to rapid death by those exposed to the liquid termiticide. Later, Dr. Chouvenc replicated the study with whole termite colonies, containing reproductive adults, brood and different aged individuals and effectively achieved colony elimination within three months with small amount of CSI bait formulation. His study confirmed what Dr. Su found, which was secondary repellency occurs with liquid termiticide treatments because the death of exposed termites occurs so rapidly, living termites can seal off the area with termite mortality and can use other means to access structures.

Dr. Thomas Chouvenc believes these recent discoveries and the more we continue to learn about termite biology, will continue to change the way we control these destructive pests moving forward. Asian subterranean termites start swarming in early March in south Florida. This is a good time to go around and inspect trees for mud tubes and other signs of termite activity to help detect termite infestation.

Thank you to Dr. Thomas Chouvenc for his review of this article.

I have been searching all over for an explanation of why the landscaping plants that surround the entire perimeter of my property is being effected by witches broom in one form or another. I have been to the county extension and they said I, or a neighbor was using too much ground clear. Not the case from what we can see. We are not using anything on the yard because of our dogs. I've sprayed weedkiller in the cracks of the road so the city wouldn't do it in the heat of the day. Anything applied to yard has been sparingly and sparse. Mostly because of the animals. 2 years ago plants started to show up with the witches broom. Random plants, all different varieties including trees, some right next to healthy. Now it's still happening, but only to us. No one in neighborhood is having this happen. Have you ever heard of this? Please offer a suggestion.

Blue land crabs can be harvested November through the end of June. They can only be harvested by hand or with a landing or dip net. There are no chemicals registered for control of blue land crabs and it is illegal to use traps, bleach or any other chemical solutions. https://myfwc.com/fishing/saltwater/recreational/blue-land-crabs/. The only way to try to keep them from burrowing in your yard is to use some type of barrier (fence) to keep them out.

4 times I have had retina issues. Still not sure but I think it may have been caused from milkweed. one or both eyes were in pain and it looked as though I was looking through a frosted glass or heavy fog. Very scary. Dr. prescribed a steroid. It had improved results within 2 days. It was a mystery to the Dr. but as I think about it, it may have been the milkweed. Now I either wear gloves and always wash after touching the milkweed.

Witches broom is caused by a variety of different causes from mites to diseases, but all look very similar. The abnormal growth caused by these herbicides looks like witches broom, yet it is more widespread throughout the entire plant. You would need to determine what is causing the abnormal growth in your hedge plants. You can contact our Master Gardeners and/or bring in a sample to our office for identification.

In the office, I was always most productive during the early morning hours while the atmosphere was still quiet. This also allowed me to complete any unfinished work from the previous day, as well as adjust my existing agenda for the day ahead if needed. Taking short breaks and ending the day while working from home has been challenging for me at times, even though I have worked from home before. This article is a great refresher for me. Thank you!

Hi Judy, I wish you had contacted the Extension Service. Those are not Oleander Caterpillars you killed, they are Gulf Fritillary butterfly caterpillars.

I’m growing Passion Flowers. They’re so beautiful and attract and . I even have beautiful Monarch Butterflies now! Passion flower is a climbing vine and spreads everywhere. But that’s ok with me. Last year, my foliage on the vines started disappearing! I noticed this ugly worm, or orange caterpillar with black spikes all over. He was devouring the leaves so fast I couldn’t believe it! An entire vine was eaten overnight I didn’t know what they were, and I didn’t kill them because I thought they might be Monarch larvae. It’s funny...they didn’t eat any didn’t eat any other plants...just the Passion Flower. It looked awful with only vines with no leaves. So I went out there yesterday with my scissors and searched for the little suckers. I found about 50 or more and I just cut off their heads with scissors. What a hassle! And I felt so guilty for doing that...I really did. From now on, I’ll make up the mixture of stuff you guys are using to get rid of these little destroyers. Thanks!

This was a best understandable address about the hazards of trees but you make sure gutters are cleaned out so water can flow freely and not contribute to roof damage or leaks.Landscape Hurricane Preparedness should be included in your hurricane plan. Don’t wait until the last minute to prepare your landscape. It can be dangerous and debris may not get picked up in time and become another hazard. Remember, just because a tree is damaged in a storm, doesn’t mean removal is the only option. Contact a consulting arborist to do a risk assessment and determine if your tree can be saved. For more information on assessing damage and restoring trees must concern this kind of matter with the tree care company services . Thanks.

Hi Pat, Thank you for your comment. We are big proponents of integrated pest management (IPM), and one of the principles of IPM is starting with more environmentally friendly options when the decision is made to control a pest. However, in this scenario, this is the best and quickest way to control this pest. Diatomaceous earth is made from the fossilized remains of tiny, aquatic organisms called diatoms and with its abrasive sharp edges, causes insects to dry out and die by absorbing the oils and fats from the cuticle of the insect's exoskeleton. Unfortunately, it will also absorb water and moisture from the air, rendering it ineffective from a pest management perspective in the landscape with our high humidity. Additionally, Bacillus thurengiensis (Bt) is a stomach toxin that would need to be ingested by the caterpillar to be effective. Another option you could try is Spinosad, which is a natural substance made by a soil bacterium, you may have to reapply a several times for complete control. Also, there has been some negative consequences with the use of the horticultural glue in trying to control gypsy moth in a similar way. The sticky substance ended up killing the tree cambium, resulting in tree death. Please keep me posted on the method of control you use and its effectiveness.

Hi Paul, Thank you for the question. I am the new horticulture agent since Kim Gabel retired. Imidacloprid, which is a neonicotinoid, is not effective against lepidopterans (caterpillars). You could try Spinosad or a microbial insecticide with the active ingredient Bacillus thuringiensis, the strain specific to caterpillars. These will need to be sprayed early, at the first sight of an infestation. Bt is only effective against caterpillars and will not harm beneficial insects. Always follow label directions when using any pesticides. Please contact our office if you have any additional questions.

Who is the person who said that caterpillars are never "beneficial"? They ALL turn into moths or butterflies which are beneficial -- so lets kill all the caterpillars and therefore there will be no more moths and butterflies on the earth! Geezz...

About 50 of those ate my desert rose over night and started eating a corn palm too. i tried killing them with a natural pesticide I had then got nervous because they were so many so I got out he big guns and downed them. They literally ate the leaves and flowers off the whole plant over night. scared me so bad i thought they would eat the whole yard by morning

Caterpillars are never considered "beneficial", as all caterpillars feed on leaves and cause foliar damage. They are considered pests if the damage is intensive and causes harm to the plant or if the damage is unsightly. I personally don't care as long as my plants don't die.

I found the caterpillars on my Desert Rose plant and sprayed them with a mixture of minced garlic and red pepper mixed with water. They dropped right off. I was concerned that I had killed a beneficial caterpillar.

Saw a green or blue crab, bigger than two adult hands wide, in Miramar, Fl. Do they hangout in canals and lakes too. Too dark for pictures. I thought it was a beach crab, had never heard of land crabs.

The product in the link will easily control the insects and release the sooty mold that they cause. It is also natural which is a must to keep florida beautiful. It was also developed in florida.

In Key West can you join forces with the mosquito control and add something to their spray which will help all of Key West save our hibiscus and other infected plants?

Regarding the Hibiscus Mealybug...I just recently moved back to SW Fl from out of state and purchased an older home with mature landscaping. There are several hibiscus and one was under severe attack from mealy bugs. I'm an organic gardener, so I wasnt interested in pesticides. I checked out the horticultural oils, but decided to try EMs (effective microorganisms). I didnt know if it would work, but I'm happy to report that one month later, I have lots of new growth and beautiful blooms. The mealybugs and the resulting damage (sooty, stumped branches,etc) are gone. I was pleasantly surprised, and continue to be amazed with EMs. I have no affiliation with the non profit company that makes EMs--EM America, but stumbled upon the product a couple years ago. It hasnt let me down yet. give it a try.

I've heard the BEST way to get rid of them is to get a dog.

There used to be a large land crab population at the corner of VonPhister and Whalton. Unfortunately, the city has installed injection wells at the same corner and we no longer have crabs there. Is the city/public works subject to the rules listed in this blog?
