Answer: There are many recipes for home made repellents, although tobacco is not recommended. Most of them involve using red pepper and/or garlic in water with a bit of soap added to help it stick. I haven't tried these myself, so I
can't vouch for effectiveness.
For dogs and cats: Mix into a quart of water: one clove garlic (chopped), one
onion (chopped), 1 teaspoon Tabasco sauce, 1 Tablespoon
cayenne pepper or chili powder, 1/2 teaspoon dishwashing
liquid. Dribble over area to be protected. Be sure to wear
rubber gloves and be careful not to get this in your eyes or
on your skin.
For deer: This deterrent is based on
the fact that deer do not like the smell of decaying egg. Mix
in one gallon of water one egg, 1 tablespoon hot sauce, and
4 tablespoons of an anti-transpirent such as Never Wilt or
Wilt Pruf . The anti-transpirent is crucial as it keeps the
solution on for about two months.
For squirrels and other critters: Some gardeners report success using repellent
sprays, either home made garlic/pepper recipes or the
commercial type such as GetAway Squirrel and Raccoon
Repellent or even predator urines.
Others report that a pet dog or cat can
serve as a deterrent, and others resort to a combination of
methods including caging plants that seem to be particular
favorites. If digging is their main activity, you may find that a
wire mesh such as chicken wire laid over the surface or caging the plants helps.
Do be sure to test any concoction on just a few leaves, wait several days, and make sure the plant is okay before spraying it all over.
