One of the easiest ways to deter deer from your garden is to physically block them out by installing a fence around your garden or plants – but keep in mind that deer are champion jumpers, so a small fence won’t be very effective.

A gentle breeze does more than just keep you cool on a hot day: mosquitoes don’t bite when it’s windy, so turning on a fan outside makes a great natural repellent.

If you’ve spent a lot of time and effort building a beautiful backyard, there’s nothing more annoying than having little winged pests flying around and ruining the relaxing atmosphere. If mosquitoes are an issue in your garden, you might want to turn to the power of scent to help. Plants like lavender and basil have strong scents that mosquitoes don’t like, so incorporating them into your garden can help give mosquitoes the boot.

Another way to push mosquitos out of your garden is to be mindful of areas that attract them – like standing water. Dealing with drainage issues in your yard is good for your lawn’s health and can help prevent bugs from swarming. Don’t forget about keeping standing water out of things like planters or kids’ outdoor toys in the yard too.

Raccoons love to snack on garden-fresh food – but having these cute-but-aggressive creatures in your yard can put your home at risk in a number of ways. Many people don’t know that once raccoons make a nest and have babies, there are bylaws in place to protect them – and you’re stuck with your new housemates until the babies are grown. Your best bet is to keep raccoons away from your home by securing your trash and not leaving pet food outside, but you can also naturally keep raccoons out of the garden by adding light to your space. Because raccoons are nocturnal, they don’t like (and avoid) light, so outdoor lighting can help discourage foraging.

If birds are pecking at your vegetable plants, they can become real pests. Adding netting around your garden is a natural way to help – try using butterfly netting to keep birds out, but beneficial bugs in.
