DE is like baby powder or corn starch, when it's in the air it can be irritating but it settles quickly and then is not a problem. We've used it for flea and tick control for years. In our area ticks and fleas are a huge problem as we often don't get long
enough freezes to kill them off in the winter. We sprinkle it around the floor boards and under the couch cushions, all over the
yard outside, but especially around the
fence where the grass is likely to grow taller before being taken care of. It's massaged into the animals coats and pushed into the cracks around the thresh holds. When we had a really bad flea problem (away from the house for a year and they just took over) we coated the whole floor and window sills with DE, let it sit overnight and then swept it to the baseboards. Then I mopped the floor with fennel tea several times over the coarse of a month, put DE under all the couch cushions and made sure there was a nice layer behind/under every piece of furniture, we also put in flea traps (it's just a
light bulb with a stick pad under it, the light attracts the fleas which stick to the pad and die) By the end of a month we barely had any fleas and I vacuumed up all the DE and went back to our normal of treating the back yard a couple times a year and rubbing it into the animals coats a couple times a year. We also add it to their food a few times a year to "deworm" I buy ours at the
feed store, it's a common additive to
chicken feed and a 50lb bag cost us about $20 and has lasted forever!
