You can make a homemade cricket repellent by making a spray out of chili peppers, hot sauce, or garlic. These solutions have been known to repel and even kill crickets.
Use a hot pepper, such as the Bird's Eye chili, once thought to be the hottest pepper in the world. Mix together 1/2 cup of fresh chilies and 2 cups of water. If you do not have fresh chilies, you can use 2 tablespoons of hot sauce. You can use the spray both inside and outside, but if spraying plants, test a small leaf first and wait 24 hours. If there is no damage, you can proceed.
Caution should be used when working around hot peppers. Avoid touching areas around the eyes, nose, and mouth, and always be careful of spraying around areas where pets or children are.
