The answer to 'natural wasp repellent' is to use essential oils, vinegar, or soapy water to deter wasps from your home and yard. Essential oils like peppermint, lemongrass, or citronella can be effective natural repellents when applied around entry points or nesting sites. Vinegar and soapy water sprays can also help discourage wasps without using harsh chemicals.
Be sure to identify any existing wasp nests and remove them safely, as wasps can become aggressive when their nest is threatened. If you have a large or hard-to-reach nest, it's best to call a professional pest control expert to handle it properly and avoid getting stung.
