I've had a terrible problem with squirrels this past season. They carried off several of my veggie plants, and a few summer bulbs, and dug up some of my seeds. A lady up the street feeds them peanuts, so I find peanut shells all over my yard as well as random holes from their relentless digging.
Earlier this season I would sprinkle cayenne pepper all over my gardens and chase squirrels out of my garden like a crazy person. A few folks here at the office were horrified about the cayenne as they had heard that if the squirrels get the spice on their paws, they'll rub it in their eyes and scratch at their eyeballs. A Canadian Gardening colleague did a little digging and found some information from the Humane Society, which recommends cayenne pepper in the garden and I found a page online that I figure makes it OK if it’s coming from a society that protects animals. The only problem with cayenne is you have to constantly reapply after giving your garden a good soak or after it rains.
In the recent issue of Toronto Life, I read Brent Preston's memoir about becoming a farmer. Brent's battle was with groundhogs and insects. To control the destructive flea beetle from ravaging his crops, he covered his plants with row cover, a finely woven fabric that allows sun and water to pass through but keeps insects out. I'm wondering if this would help deter the squirrels from my plants and seeds–at least until they're strong and sturdy. I think I saw an example of row cover last week when I was in the Bruce Peninsula. We came across Harvest Moon Organic Bakery and Sculpture Gardens while looking for a mountain biking trail. At the end of a long driveway we came across this lovely little bakery with the most delicious treats. Part of their vegetable garden was covered in a light cloth, which appears to be row cover. I think I might try it next year.
How do you deter squirrels in your garden?
