Bought fenstar kit for bed bugs, doesnt seem to be doing the job so I bought zenprox. Will the two react together in any way or make the zenprox less effective?
Both Fenvastar and Zenprox are non-repellents and three weeks time has passed therefore there should not be any counteraction between the two.
