MADISON, Wis. – The Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) will be setting more than 10,000 traps for spongy moth, formerly known as gypsy moth, in 47 counties from mid-May through early June. DATCP requests that property owners allow trappers access to place traps and not disturb the traps once in place.
“The data we gather from these traps provide an estimate of the state’s spongy moth population and is used to plan for next year’s spray treatment,” said Michael Falk, DATCP Spongy Moth Program Manager. “It also helps DATCP nursery and Christmas tree inspectors check trees for spongy moth egg masses in the fall.”
Traps are small green boxes tied to tree branches. The trap contains the scent of a female spongy moth that is undetectable to other insects and is used to attract and catch adult male spongy moths.
Trappers will monitor traps until male moths stop flying and the traps are removed in August. Trappers wear fluorescent vests and carry identification cards. Each trap is labeled with a phone number that property owners can call if they have questions or decide they want it removed.
