MADISON, Wis. (WRN) — Statewide surveys for invasive spongy moths are set to begin.

From mid-May through early July, the Department of Ag, Trade and Consumer Protection will be setting approximately 8,000 traps for spongy moths across 36 counties. Most traps will be set along public roads, but some will require placement on private property.

DATCP asks that if you come across a spongy moth trap, which are small green boxes stapled or tied to trees, to leave it be. The data collected from the traps is crucial to helping limit the spread of the invasive species.

More info on spongy moth trapping can be found on DATCP’s website.
