Squirrels may be enjoyable to watch on a warm summer day, but if you are a gardener, they are often your nemesis–eating vegetable and fruit crops, such as your tasty homegrown tomatoes. There are many home remedies, such as sprinkling cayenne pepper, that claim to help, often they do not. Building a cage around your plants is the one sure way to keep the squirrels away from your tomatoes.
Buy chicken wire that is tall enough to accommodate the mature height of your tomato plants.
Cut off the bottom horizontal row of the chicken wire with bolt cutters. Now the bottom vertical pieces will be jutting out.
Stick the bottom vertical wires into the soil, encircling your tomato plant with the chicken wire cage.
Insert four stakes (wooden or plastic) around the cage you just installed. The stakes should be a couple inches higher than the cage.
Lay bird netting over the stakes and tie the netting around the stakes and around the cage with twine.
