Traps in cotton fields are checked weekly during the eradication phase of the program. Quality control checks include checking dates on traps, changing lure colors, and placing dead marked weevils or other objects in traps. Program scouts check and maintain the traps until the producer destroys the cotton stalks or weather terminates the crop. A few traps stay in the fields through the winter so that weevil populations can be compared from season to season. After the eradication program is finished, trapping continues at a reduced rate.
Scouts check the traps every two weeks.
If weevils are captured, program officials increase trapping and apply treatments when necessary to prevent reinfestation.
