Are Gypsy Moth Caterpillars Dangerous?

Gypsy moth caterpillars are dangerous to gardens, yards, crops, and greenery.

Gypsy moth caterpillars can eat trees or plants for several weeks. During this duration, these caterpillars can cause a lot of damage to the trees or plants they ate from, often eating all their leaves.

In the early summer months, between June and July, they enter the pupal stage, where they transform into adult moths. 

Once a gypsy moth caterpillar attaches itself to a tree or any plant, the larvae start eating the new spring foliage. The damage these caterpillars cause increases each time they grow in size and procreate.

What Do Gypsy Moths Eat?

Adults aren’t as dangerous to gardens, farms, and crops as their larvae are.

The young caterpillar larvae of the gypsy moths are dangerous to trees, they drill small holes in the leaves they eat, and their holes are in the middle of the leaf.
