If you’re using baits and not achieving effective control, try placing two different types of baits on a business card. Place the card behind the refrigerator or by the closest harborage where it won’t be disturbed. Putting the baits on a card makes it easier to take them out and examine them to determine what might be going on. Come back in 24 hours to check it. If both baits are completely gone, you’re probably underbaiting. If only one bait has been eaten, you’re probably dealing with bait aversion.
