They may look harmless, even a little fuzzy, but the buck moth caterpillar is anything but friendly.
As spring settles in across Louisiana, these stinging caterpillars are making their seasonal appearance, and experts say now is the time to be cautious.
LSU AgCenter entomologist Aaron Ashbrook says there’s a brief window when they are easier to manage.
“When they’re grouped together, you have a better chance of treating or removing them,” Ashbrook said. “Once they scatter, it really doesn’t make much sense to try.”
And while many people think of insect bites this time of year, Ashbrook says this is something different.
“You’re not getting bitten, you’re getting stung,” he said. “Those hairs you see are actually connected to venom sacs.”
If you come into contact with one, you’ll likely feel it right away.
Experts recommend treating the area quickly. Over-the-counter antihistamines like Benadryl can help reduce reactions, and using tape to gently remove the tiny spines from the skin may also provide relief.
But in more serious cases, it’s important to act fast.
“If you start feeling dizzy, develop a fever, or have trouble breathing, seek emergency care immediately,” Ashbrook said.
As for avoiding them in the first place, the advice is simple, and a little blunt.
“Run,” he said.
With more people spending time outdoors this season, awareness is key. A quick look before you touch tree trunks, branches, or outdoor surfaces could save you from a painful encounter.
