Aztec Organic Pest Service Austin, TX

We have an excellent flea program using boric acid inside and nematodes outside. Boric acid is less toxic than table salt, odorless and non-staining. This is a layman's explanation of how pets and fleas are related. Boric acid is preferable to spraying as it is more pervasive and thus less likely to miss the egg or larva. A boric acid for roaches is available at many stores - 99% boric acid, 1% inert ingredient is the best as the inert ingredient keeps it from crystallizing due to humidity - thus it lasts much longer.
