Which option is the most commonly used for roach control?

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

Answer: (B)

Using bait is the most common approach for roach control because it directly targets the roaches where they feed and live. Baits attract multiple individuals, including those hidden in cracks and voids, and the toxin is slow-acting. This allows the roaches to share and transport poisoned material back to the colony, spreading the effect beyond the initial feeders and reducing the population over time. Baits are practical indoors, stay in place, and can be used alongside sanitation and sealing to boost overall effectiveness while minimizing exposure to people and pets. In contrast, aerosols kill only the roaches they contact, often missing hidden harborages; traps mainly monitor or capture rather than substantially lower numbers; and exclusion helps prevent new invasions but doesn’t eliminate an established infestation.
