Crack and crevice treatment uses low pressure and a fine stream.

• A. True
• B. Uses high pressure
• C. Uses spray foam
• D. False

Answer: (B)

Crack and crevice treatment targets pests hidden in narrow openings by delivering the product with a low-pressure, fine stream. This combination lets the liquid reach tiny gaps and voids without forcing it back out or creating excessive drift to surrounding surfaces. Using high pressure would create larger droplets, increase drift, and reduce precision, making the treatment less controllable. Spray foam isn’t used for applying liquid pesticides to cracks; it’s a sealant used to block voids, so it doesn’t fit the method of crack and crevice treatment. So, the approach of low pressure with a fine stream is the correct way to apply in these tight spaces.
