Gypsy Moth Infestation

Gypsy Moth Invasion
by Barbara Fradkin, SLPOA Environmental Issues Co-ordinator

There is a huge gypsy moth infestation this spring, which not only creates a mess and defoliates the trees, but also weakens them, potentially killing them, and reduces the habitat and food supply of other wildlife.
In the absence of large-scale aerial spraying, there are some steps that individual property owners can take to try to control the damage on their own property. Knowing the gypsy moth’s life cycle is important to knowing how to manage its spread. There are four main stages of the gypsy moth lifecycle: larva/caterpillar, pupa, adult moths, egg masses. Scroll down for specific stage-centric methods to capture and remove gypsy moths and limit the pest’s spread.

To manage gypsy moth:

May to July: Hand Pick Caterpillars

June – August (Larger caterpillar stage): Burlap Banding
. Once the caterpillars grow to about an inch (2.5 cm) in length by mid-June, they will move down the trunk to seek shelter from predators and heat during the day. Reduce the number of larvae on the trees in your yard by trapping them.

Required Supplies
• Burlap cloth
• Twine or rope
• Bucket of soapy water. Dish soap works well

Step-by-Step Instructions: Wrap and secure a piece of burlap cloth around the stem/trunk of your tree. Tie twine or rope around the center or slightly below the centre of the burlap. Drape the burlap cloth over the twine or rope so there is an overhang where the caterpillars can crawl underneath to seek shelter during the day. Check the trap by lifting the overhanging burlap cloth every afternoon and collect any hiding caterpillars. Put them into a bucket of soapy water for a few days to destroy them. Doubling up duct tape to expose the sticky side is also helpful.

July – August (Female Moth stage): Burlap Wrapping
 to Trap Female Moths: Wrap burlap lower on the trunk of the tree to trap the female moth (which are unable to fly) before it crawls up the tree and lays eggs. This is the same method used for the larger caterpillar stage. Once captured, drown the moths in soapy water.

July – August (Male Moth stage): Hang Pheromone Traps. 
Hang pheromone traps in trees to attract male moths, which prevents them from mating with female moths and producing eggs. Once captured, drown the moths in soapy water.

November – late April (Egg stage): Destroy Egg Masses. 
Survey your property for egg masses and scrape them off surfaces into soapy water to destroy them.

Required Supplies
• A flat object such as a butter knife or plastic paint scraper
• Catchment container or bag to collect the egg masses
• Bucket of soapy water. Dish soap works well

Step-by-Step Instructions: Place your catchment container below the egg mass. Use your scraper tool to remove the egg mass from the surface. Ensure that all eggs are scraped. Try not to leave any residual eggs in bark ridges or crevices. Empty the contents of your catchment container or bag into a bucket of soapy water. Leave the eggs sitting in the bucket for a day or two, then dispose of the contents. Egg masses can be located high up in trees. Take care, especially if using ladders. Some private tree care companies can be hired to provide this service at heights.

Hello All,

Although the city approach is a good approach for control of small Gypsy Moth Infestation; the only true way to control a large infestation is by Aerial application.

I direct you to the Zimmer Air Website Who is highly experienced in Aerial application for the control of Gypsy Moth Infestation.

They use Foray 48B which is a safe Biological Insecticide. Go on the website today under Services/ Aerial Applications / Forest Pest Control.

Timing is critical. Get a head of the 2021 year.
