How To Check For Gypsy Moths

How To Check For Gypsy Moths

Gypsy moths are an invasive and destructive pest that often come back year after year. Their egg masses are typically found anytime between July and April and eventually hatch into caterpillars that are covered with hair and can be characterized by five pairs of blue dots and 6 pairs of red dots running down their backs. These caterpillars eventually transition into the pupae stage in which they metamorphose into winged gypsy moths, and the cycle repeats!


Gypsy moths have an extremely large appetite for more than 300 species of trees and shrubs, making them a danger to forests. The gypsy moth caterpillars work hard in defoliating trees, leading to trees dying due to their vulnerability to diseases and other pests.


If you have trees on your lawn or garden, they are at risk of being damaged by gypsy moths every year. But how does one check if they have them around their home? We’ve listed the places you need to check and the signs you need to look out for in order to find out if you have a gypsy moth infestation around your home. Keep on reading!
