Gov. Jay Inslee issued an emergency proclamation today due to the imminent danger of an infestation of the non-native plant pests spongy moth (Lymantria dispar L.), formerly known as the gypsy moth. The imminent infestation is in the Steamboat Island Road and US Highway 101, Thurston County area (roughly 1,383 acres), and also near the town of Concrete, Skagit County area (roughly 920 acres).

This imminent danger of infestation seriously endangers the agricultural and horticultural industries of the state of Washington and seriously threatens the economic well-being and quality of life of state residents. This order directs the Director of the Department of Agriculture to use emergency measures as necessary in the above noted areas to effect the eradication of the spongy moth, which may include the use of aerial spray applications anticipated to commence mid-May 2024
