Which non-chemical method is used for cockroach control?

• A. Placing sticky traps
• B. Vacuum
• C. Sealing cracks and crevices
• D. Gel bait

Answer: (B)

Non-chemical control methods rely on removing pests and limiting their harborage rather than using pesticides. Using a vacuum directly removes roaches from visible areas and hiding spots, giving an immediate reduction in numbers without any residues. It’s especially helpful for quick cleanup in problem spots like kitchens and behind appliances, and it also clears crumbs and debris that roaches feed on. Placing sticky traps can help detect activity and capture some individuals, but they don’t rapidly reduce a live infestation. Sealing cracks and crevices is preventive, reducing access and hiding places, but it doesn’t remove roaches that are already present. Gel bait uses insecticides, so it’s not a non-chemical method. So, vacuuming roaches provides the most immediate non-chemical control among the options.
