Once I mix the Onslaught with the bait, how long will the effectiveness of the Onslaught last?
The Onslaught itself will stay effective for several weeks but the yellow jackets may ignore old bait that is spoiled or moldy. Yellow jackets tend to go for fresh bait. We recommend changing out old, spoiled or moldy bait for best results.
