The presence of emerald ash borer (Agrilus planipennis) has been confirmed in Louisiana, bringing to 25 the number of states affected by the ravenous pest.

During a survey of ash trees in Webster Parish, a U.S. Forest Service and Forest Health Protection employee found evidence of EAB; further investigation revealed larvae nestled comfortably beneath the bark of several trees within a two-acre area. Webster Parish is located in the northwestern part of the state, to the north and east of Shreveport.

EAB had been spotted in 2014 in neighboring Arkansas, and the Louisiana Department of Agriculture and Forestry drafted an EAB response plan last fall, but the LDAF had begun surveying for EAB—using sticky traps—about seven years ago.
