2021 Proposed Gypsy Moth Treatments

ALLAMAKEE AND CLAYTON COUNTIES

The Iowa Department of Agriculture and Land Stewardship, in collaboration with the USDA Forest Service and the Iowa Department of Natural Resources, plan to treat localized gypsy moth populations in Allamakee and Clayton Counties during late June. Management plans involve the aerial application of a gypsy moth specific mating disruptant called SPLAT GM-O.

SPLAT GM-O is an organic formulation used specifically for the control of gypsy moth using mating disruption. It uses a sex pheromone to deter males from mating with female gypsy moths. SPLAT GM-O is made entirely of food grade materials and is certified organic under USDA's National Organic Program. For more information about the gypsy moth and treatment plans, you can watch a video presentation by clicking on the embedded video below.

The timing of treatment is dependent on environmental conditions and insect development. For the most up-to-date treatment schedule this website can be checked periodically. Iowa's Gypsy Moth line can also be reached by calling 855-497-7966 or 515-725-1464 to listen to a recorded message of the latest treatment schedule. If you live in or near a treatment area, you should receive a postcard approximately 1 - 2 weeks prior to treatment with the tentative treatment date and contact information.
