Spiders inside the home are a real problem, especially in the winter and colder months. Removing them is usually easy but preventing them from coming in is even better. Using vinegar around the home keeps the spiders away without harming them.
Vinegar is a natural spider repellent and is safe to use in homes with pets and children. Vinegar is less expensive than many common chemical preparations and the vinegar smell does not linger once it dries.
Spiders hate the smell of vinegar, making it an effective deterrent indoors. Vinegar is most effective when it is used regularly, two to three times per month. Vinegar is ineffective as a spider repellent when used outdoors because it is easily diluted or washed away by rain.
Mix one part pure vanilla extract and three parts full-strength white distilled vinegar in a spray bottle. Spray the mixture into the dark corners of closets and cabinets. Wipe undiluted vinegar on window sills and door jambs to prevent spiders from coming in through small cracks.
