I applied Advion Roach Gel Bait two week ago with two results and I've read that you have to remove old gel before applying new gel. I understand the need to remove the old gel so that the roaches will be attracted to the fresh one, but if I don't intend to re-apply and I don't remove the old gel, will it cause problems?
The only real con to leaving old Advion Cockroach Gel Bait in place is that it can become very hard to remove from the surface it was applied to.
