The answer to 'DIY spider control' is that there are several effective DIY methods for controlling spiders in and around your home. The first step is to identify the type of spider you're dealing with, as that will determine the best approach. For common household spiders, you can start by vacuuming up any webs and egg sacs you find, then sealing up entry points like cracks and crevices to prevent them from coming back.
You can also use a natural spider repellent spray made with essential oils like peppermint, eucalyptus, or citronella. Apply it around windows, doors, and other areas where spiders tend to congregate. For more severe infestations, you may need to use a targeted insecticide spray, but be sure to follow the instructions carefully and take necessary safety precautions.
