Do the plastic packets dissolve without opening them?
Yes, Demon WP packets will dissolve when mixed with water in a hand pump sprayer and applied to cracks and crevices listed on the product label. It would help to fill the spray tank 1/2 with water and dissolve a packet of Demon WP and add another 1/2 gallon of water.
