The answer to 'DIY cricket control' is to use a combination of exclusion, trapping, and targeted insecticide treatments. Crickets can be difficult to control, so a multi-pronged approach is often necessary to effectively eliminate them from your home.
Start by sealing any cracks and crevices where crickets may be entering your home using caulk or other sealants. This will help prevent them from getting inside in the first place. You can also use traps baited with food or pheromones to capture and remove adult crickets. For more severe infestations, you may need to use targeted insecticide treatments in problem areas. Always follow the product instructions carefully and take proper safety precautions when using any pesticides.
