Bifen IT will help control boxelder bugs. You want to mix at 1oz Bifen IT per gallon water. Bifen IT will kill the Boxelder bugs after they come in contact with the treated area. Depending on what stage they are in the life cycle will determine how long it will take to kill them. The residual of Bifen IT can be up to 2 months, but it is best to reapply every 30 days.
