The spongy moth (Lymantria dispar) is an invasive species that feeds on deciduous and coniferous trees causing destruction. Currently, there is a significant increase in the presence of spongy moths within our communities.

During the spongy moth's larvae stage, the long hairs of the caterpillar can cause skin irritation or more severe allergic reactions similar to contact dermatitis. You may feel an itching, stinging, or burning sensation. The irritation may last a few days to two weeks. Tape can be used to remove any larvae hairs on the skin to prevent further skin reactions. After the affected area has been washed with soap and water, speak to your health care provider for treatment options.

You can learn more about the prevention and control of the spongy moths from the Government of Ontario website.
