TreeHelp Spongy (Gypsy) Moth Trap (Reusable)

The TreeHelp Gypsy Moth Trap is a reusable pheromone trap that catches adult male gypsy moths during the summer mating season, before they can mate. Used over several seasons, it is an effective tool for reducing overall moth and caterpillar populations.

What is included?

• One Gypsy Moth Trap
• One Gypsy Moth Lure (refrigerate until use)

Why trap gypsy moths?

Gypsy moths are one of the most destructive pests of our urban forests, stripping oak, crab apple, poplars and hundreds of other trees and shrubs. Each mated female can produce as many as 1,000 caterpillars the following spring. Those caterpillars can strip your shade trees and ornamentals bare, leaving them more vulnerable to secondary attack by other insects and diseases that can kill them.

The trap is designed to help you avoid applying pesticides indiscriminately. It is simple and easy to use, and its powerful pheromone lure attracts gypsy moths and detects outbreaks, so you can use less pesticide.

How does the trap work?

The trap disrupts the gypsy moth's reproductive cycle by attracting and trapping adult males before mating can occur. The female gypsy moth does not fly; instead she releases minute amounts of a sex lure (pheromone) to attract the flying male. The trap's special attractant releases a highly purified form of this sex lure and pulls male moths in from a ¼-acre area, trapping them before they reach the waiting female.

When and where should I hang it?

Hang the trap first in spring, shortly after the caterpillars emerge (moth or larva stage). It is effective as long as the moths are active, from late April through late September.

• Choose a tree, and a spot on the tree, where air currents can freely carry the scent of the attractant.
• Hang the trap from a tree or place it on a stand about 4 to 5 feet off the ground.
• The south side of the tree is the best location.

Should I use other controls too?

Yes. For best results, use the trap as part of an Integrated Pest Management program that also includes biological treatments such as BTK, or other sprays and traps such as bug bands, against caterpillars.
