... But honestly I wouldn't Use seven dust as your monthly flea treatment. However,I tend to take in any hungry dog that rolls up. Many were COVERED in ticks and flease. I was given this advise and it has served me well, get a bottle of Adams and a thing of seven dust. Spray the entire dogs with Adams, apply liberally to the area with a lot of ticks. While the dog is still wet sprinkle seven dust on the dog and rub it in. Coat the bottom of the kennel or just the doghouse if theyre on a cable with the seven dust. Within 3days almost everything is gone or dead if they're still attached. Then go to the Bayer soon after as a preventive....this is mainly for heavy tick problems. I'm no vet but It works and hAsnt hurt a dog so far and some of them looked like hairy skeletons when I did it.
