When you are using Advion Roach Bait Gel, you are placing 3 to 5 spots of ADVION cockroach gel bait per 10 linear feet for heavy infestations. It is recommended that you wipe up the bait after 2 weeks and re-apply it so that the roaches have fresh bait to consume. Once you have gotten rid of the infestation, the bait can be replaced every 3 months or when bait is gone.
