To perform pest control at home by yourself, start by identifying the type of pest you’re dealing with. Once identified, you can use simple DIY methods like traps, sprays, or natural repellents. For example, sealing cracks, setting up bait stations, using essential oils (such as peppermint or tea tree oil), or using homemade vinegar solutions can help manage common household pests like ants, roaches, and spiders. Regular cleaning, proper waste disposal, and maintaining a dry environment are also crucial in keeping pests away.
