Use Advion Evolution as a clean out bait, then begin to rotate other baits such as Optigard Cockroach Bait, Maxforce FC Magnum, Invict Gold, or Vendetta Plus. To avoid bait aversion and resistance, we recommend rotating with 3 different baits. Cockroaches adapt very quickly. If the first bait does not work, the second or third will.
