Which solution is effective for flushing pests from hiding?

Using a lemon scented dishwashing detergent solution is effective for flushing pests from hiding due to its surfactant properties. Surfactants break down the surface tension of water, allowing it to penetrate and spread more effectively across surfaces, including plant leaves where pests may be hiding. The detergent can help dislodge pests by creating a slippery layer that makes it difficult for them to maintain their grip, encouraging them to come out of their hiding spots.

Additionally, the lemon scent can act as a mild attractant or irritant to certain pests, prompting them to relocate. The soap can also suffocate soft-bodied insects by clogging their spiracles, which are the openings used for breathing, further aiding in pest management efforts.

Other solutions may not have the same efficacy in flushing pests. Salt water can harm plant tissue and lead to further issues for the plants, vinegar can be overly acidic, damaging plant health, and alcohol may evaporate quickly, not providing sustained contact or effectiveness in flushing pests.
