I sprayed
for fleas last week and now they are back. Why didn't the spray work?
Even sprays that contain insecticides and growth
inhibitors have difficulty penetrating the pupae cocoon. Flea larva that
have entered a cocoon state will require follow up applications of the
insecticides after they hatch. This is usually a 3 or 4 week process.
For much more information, Fleas is a great place to look.
What can you do about bad odors in the carpet from dogs?
You need a product that can break down the malodors. A product
such as Davis Odor Destroyer®,
sprayed on the soiled area or generally broadcasted will work.
