I bought a product called Only Natural Pet All in One Flea Remedy and the primary ingredient is DE. It seems to work on the dog and cat and in the house. I would like to apply outdoors around the door the dogs come in though, and the instructions state that it can be mixed with water, sprayed on and will become active when dried. Everything I have read here indicates once DE is wet it's not going to work... what do you think of applying it in water and it drying out? I live in Ohio and it's pretty humid out all summer. I only prefer to spray it on because it is much easier than trying to sprinkle it around the yard and get a uniform coverage. I guess I need to go buy 50 POUNDS of it huh?
