Puss Caterpillar

How To Control Puss Caterpillars

While some caterpillars are harmless, there are some stinging caterpillars which exist and coming in contact with them could make you wind up in the hospital. This is especially the case with the dangerous and venomous Puss Caterpillars.

Measuring 34 to 36 mm in length, puss caterpillars (Megalopyge opercularis) are extremely venomous critters which vary in color from grayish-white, to orangish-brown, to charcoal. When they reach adulthood, they turn into yellow or orange moths with black, furry feet.

Puss caterpillars become common during the late summer, early fall months and have become an increasing problem in the United States in places like New Jersey, Florida and Texas. The bugs tend to gather around around oak, elm and citrus trees, as well as in garden plants like roses and ivy.

Why Buy These Products

Coming in contact with the furry Puss Caterpillar on your lawn or garden can be quite a scary encounter because of the sting they deliver just from merely touching their fur. The Puss Caterpillar’s fur is covered with venom which causes intense pain when touched by skin. The sting is said to be more painful than the sting of a jellyfish or scorpion and can result in symptoms of vomiting, convulsions and a drop in blood pressure. It’s safe to say that just by the thought of getting stung by this creature is enough to want to do whatever it takes to eliminate it from your yard.


At Solutions Pest and Lawn, we have all the tools necessary to eliminate this dangerous pest and can also provide you helpful advice online, live in person at our stores or over the phone to guide you through an effective treatment process to get rid of puss caterpillars from your property.


How To Get Rid of Puss Caterpillars - Solutions 4 Step Process

Puss Caterpillars are more of a concern outside of the house in gardens and flowerbeds. It’d be a rarity that they make their way inside a home. For best results, Solutions experts recommend that a combination of both chemical and organic control methods be applied to achieve total elimination of the insect.  


While using the professional-grade products we provide can go a long way in reducing the puss caterpillar populations, to achieve long-term control you will have to make your property less appealing to puss caterpillars.


Step 1: Whatever you do, do NOT touch a puss caterpillar without proper protection. If you are ever to encounter one outdoors, use an object such as a stick if you need to remove one of these caterpillars from a plant or from your body. Heavy leather gloves are another option, but caution should be used.


Step 2: If you choose to handpick the puss caterpillar with gloves, you can kill them by putting them in a bucket of soapy water. Dispose of the now-venom contaminated water by flushing it down the drain and also wash or get rid of those gloves.


Step 3: For invasions in the home or outdoors in the garden, an insecticide containing Bifenthrin or permethrin such as Acelepryn G Insecticide or Essentria IC3 Natural Pesticide can provide long lasting control. Mix these products into a hand sprayer and treat all around the foundation both indoors and outdoors. Spend most of your focus treating the outside.


There are also dusts which you can use that are effective in killing puss caterpillars and keeping them away like Essentria D Dust Insecticide and others.


Step 4: Once the puss caterpillar infestation has been controlled, put into place exclusion measures to keep puss caterpillars and other small pests from coming into your home by placing tight-fitting screens up, weatherstripping around doors and windows, and sealing up cracks and crevices with caulk.
