The most common product used for roach control is?

• A. Bait
• B. Aerosol
• C. Traps
• D. Exclusion

Answer: (A)

Bait is used most often for cockroach control because it leverages the roaches’ feeding habits and social behavior to kill more of the population. Baits attract roaches with food-like attractants and deliver a slow-acting insecticide. When a roach feeds, it often carries trace amounts back to the nest, contaminating others and reaching harborage areas that sprays may miss. This creates a broader, longer-lasting effect than treatments that rely on contact alone.

Aerosols provide quick knockdown but don’t reach hidden roaches or provide lasting residual control, especially in cracks and voids. Traps mainly monitor numbers and can reduce a few individuals, but they don’t solve larger infestations. Exclusion blocks new arrivals but doesn’t reduce the roaches already present.

So, bait is the most common and effective option for overall roach control.
