Keeping Grasshoppers Away: an activity for children of all ages. Grasshoppers are amazing little creatures, but not ones that you want in your garden. In this activity, children will learn several ways to keep grasshoppers out of the garden. Note: you may need to implement several of these solutions to get effective results.
- Supplies (you may not need all of these)
- Garlic oil and neem oil can be diluted and sprayed onto the leaves of your plants to repel grasshoppers.
- Flour can be sprinkled onto damp leaves. Once the grasshoppers eat the flour it gums up their mouths.
- Praying mantis can be purchased online or at your local gardening store. They simply prey on grasshoppers and reduce their numbers. Make sure to follow the instructions for release once you get them.
- Any of the plants listed in the supplies can be used to repel grasshoppers. They work best as a barrier when planted completely around the plants you’re trying to protect. The wider the barrier, the better the protection.
- Blue birds are natural predators of grasshoppers and are easy to attract to your garden. Mount bluebird houses on poles about five feet high in a sunny spot in your garden. Make sure you have water sources available as well. If you don’t have blue birds in your area, check with your local gardeners regarding what birds are good for eating insects and what you can do to attract them.
- Nosema is a spray that infects young grasshoppers with a parasite. It is not very effective on older grasshoppers and has a short shelf life, so spray early and buy it right before you use it.
- Insect barrier is simply fabric that can be draped over your plants to keep insects out. Take note that this will also keep out pollinators so you have to time its use correctly (after the flowers are pollinated and before the grasshoppers appear) or do hand pollinating. However, if you are growing leafy greens which don’t need to be pollinated, this may be a very simple and easy solution.
