Ontario is experiencing an overwhelming infestation of Gypsy Moths this season and this means that your trees are at risk of being quickly defoliated!
These caterpillars feed on deciduous trees at an alarming rate! One caterpillar can eat its way through a square metre of leaves as it grows into its adult form!
Gypsy Moths prefer Maple, Beech, Birch, Ash, Poplar, Oak and more! They can also move on to softwoods such as Eastern White Pine, Balsam Fir and Colorado Blue Spruce trees when their deciduous buffet is exhausted!
1. Pressure wash the trunk and main branches of your trees to dislodge the caterpillars.
2. Hand remove any visible caterpillars.
3. Apply a band of caterpillar tape or duct tape inside out on the tree trunks. Caterpillars travel up and down the trunk and will become stuck on the sticky tape.
***** VERY IMPORTANT!!! When using this method please add a layer of chicken wire or mesh to the outside of the duct tape to prevent wildlife from accidentally becoming trapped.
4. Create a burlap trap on trees with heavy caterpillar traffic:
