Those green and orange gypsy moth traps are coming back for the 29th consecutive year.
Residents will see the traps in force along Olympic Peninsula roads.
More of the triangular traps are being placed in Clallam and Jefferson counties than last year.
That is with good reason, according to state officials.
Port Ludlow in East Jefferson County was one site of three gypsy moth outbreaks found last year.
Eradication of the caterpillar form of the moth took place in the spring.
Crews applied three treatments of a biological agent on trees in the village to kill the invasive pest.
“We’ve kept permanent populations of gypsy moth out of the state for 30 years, and we want to continue that record,” Clallam and Jefferson trapping supervisor Harold Frost said last week.
“You can’t eradicate what you can’t find.”To help find the moths, 1,550 traps will be placed on the Olympic Peninsula, with an additional 750 in Kitsap County across Hood Canal.
