I'm not sure if it will help the kennels but Flies hate baby power , I sprinkle some on the dogs if the flies start to get real bad on the dogs. Works for only about 2 to 3 days but work right away every time! I know there's all kinds of fly spray but for a dollar it's just something worth keeping around.
never heard of that will it work on fleas I've started using ultrasheild it works good kinda pricey.
