Throughout Georgia each year, homeowners occasionally discover unusual fuzzy caterpillars crawling along exterior walls, resting on ornamental shrubs, hiding around patio furniture, or attached to small trees and landscaping around the property. Many people assume these insects are harmless because of their soft hair-like appearance, but one species in particular has gained attention across the South for its painful sting — the Southern Flannel Moth caterpillar, commonly known as the “Puss Caterpillar.”
Why Homeowners Should Avoid Touching These Fuzzy Caterpillars
The Southern Flannel Moth caterpillar is considered one of the more medically significant stinging caterpillars found in the southeastern United States. These caterpillars are covered with dense hair-like fuzz that hides venomous spines underneath the surface. Direct contact with these spines can cause intense burning pain, swelling, skin irritation, and in some cases more serious reactions depending on the individual and level of exposure.
At Cardinal Pest Management, customers occasionally contact us after discovering these unusual fuzzy caterpillars on:
Why Homeowners Commonly Find Them Around The Home
Near entryways and landscaping
Shrubs and bushes
Ornamental trees
Exterior siding and walls
Porch railings
Patio furniture
Outdoor decorations
The caterpillars are often noticed while homeowners are trimming bushes, gardening, pressure washing, or performing routine outdoor maintenance around the home.
Because the caterpillar looks soft and harmless, children and even adults may attempt to touch or pick them up without realizing the risks associated with their venomous spines.
The Powerful Sting Behind The Fuzzy Appearance
The Southern Flannel Moth caterpillar receives media attention throughout the South several times each year because of its unusually painful sting. Hidden beneath the soft outer hairs are venomous spines connected to poison glands. When touched, these spines break off into the skin and release venom that may cause:
Burning pain
Redness and swelling
Rash-like irritation
Nausea in some cases
Headaches
Sensitivity around the affected area
Pain from the sting can sometimes radiate outward from the contact point and remain uncomfortable for several hours.
While serious medical reactions are less common, individuals with allergies or sensitivities should seek medical attention if symptoms become severe.
Southern Flannel Moth Biology & Habitat
The Southern Flannel Moth caterpillar is the immature stage of a small moth species commonly found throughout Georgia and much of the southeastern United States. These caterpillars prefer warm humid environments and are often associated with:
Shade trees
Shrubs
Woodland edges
Landscaped residential areas
Parks and gardens
The larvae feed on leaves from a variety of trees and ornamental plants before eventually forming cocoons and developing into adult moths.
Adult Southern Flannel Moths are generally small, yellowish to cream colored moths with dense hair covering their bodies. Most homeowners notice the caterpillar stage far more often than the adult moth itself.
What To Do If You Find One
If you discover a Southern Flannel Moth caterpillar around your home or landscaping:
Avoid touching it directly
Keep children and pets away from the area
Wear gloves when working around affected shrubs or plants
Use caution when trimming vegetation where caterpillars may be hiding
In some situations, populations may become more noticeable during warmer months when caterpillars are actively feeding and moving around vegetation.
Georgia Homeowners Should Stay Aware During Summer
As summer temperatures continue rising throughout Metro Atlanta and Northwest Georgia, homeowners are spending more time outdoors gardening, maintaining landscaping, and enjoying outdoor living spaces. This is also the time when stinging caterpillars and other seasonal pests become more active around residential properties.
Cardinal Pest Management believes education is an important part of helping homeowners identify and understand unusual pest and insect activity around the property. Many insects found around homes are harmless, while others — like the Southern Flannel Moth caterpillar — deserve caution and respect due to their venomous defensive spines.
