While most spiders are completely harmless, many people would still rather them not be in their homes. Here are four effective ways of deterring spiders from your home. Seal Any Potential Entry Gaps Spiders can find a way into your home using the smallest of gaps. It's worth looking around your house and sealing any tiny gaps that a spider could use to infiltrate your home. Make A Peppermint Oil Spray Peppermint oil is the best option to effectively repel spiders permanently. This is because spiders smell through their legs and the overpowering scent of peppermint will send them scrambling. Use Citronella Scented Candles Citronella candles are commonly used in the summer months to keep wasps and mosquitos away. But during the winter months, they can help keep spiders out of your home too. A White Vinegar Spray White vinegar isn't just great for cleaning, it is also effective at repelling spiders from your home. Try spraying half water and half vinegar over windows and other entrances where bugs and spiders could be sneaking in.
