Browntail Moths Are Showing Up All Over The Place

July 17, 2023

The larval stage of the browntail moth is a significant nuisance for Maine residents, causing health issues and damaging trees. And now that they’ve entered their moth phase and have left the trees, they’re showing up everywhere. In this blog post, we’ll discuss what this means for the coming winter and what property owners can do to protect their families and trees from these invasive insects.

When the moth phase begins & where you’re likely to see these pests 

Browntail moths go through several stages in their life cycle. The adult moths are white in color, with noticeable tufts of brown hair on their bodies. They typically emerge in late June or early July. During this time, you may see these white moths on the sides of your home, around exterior lighting at night, and elsewhere around your home and property. 

What does it mean if you notice browntail moths on your property this summer?

While you don’t have to worry about adult moths causing damage or even posing any kind of direct health threat, it’s important to note that their presence on your property now means you’re likely to see winter nests in your trees once the cold weather arrives. 

Here's why that’s a problem for Mainers

The real concern lies with the browntail moth caterpillars. In the spring, the female moths lay eggs on the undersides of leaves. These eggs hatch into caterpillars in late April or early May. The caterpillars have distinctive brown tufts of hair and are known for their ability to release irritating hairs that can cause skin rashes, respiratory issues, and eye irritation in humans. 

The caterpillars also cause damage when they feed on a wide range of trees, including oak, apple, birch, and other hardwood species.
