The key to using garlic to prevent ticks is to use fresh garlic at the rate
of one gousse per day - ie one of the segments rather than the whole bulb.
This can be minced and added to food. Garlic tablets or capsules are
useless.Even so, garlic is not 100% effective. Nothing is, but garlic is as
effective as the veterinary products and has no nasty side effects.
