There are many ways to keep spiders out of your house, but the most effective methods are exclusion techniques such as caulking up cracks and crevices, using weather stripping around doors and windows, and making sure that there is no debris or clutter in your yard that could serve as a hiding place for spiders. You can also use chemical repellents such as peppermint oil or diatomaceous earth to keep spiders away from your home. These products work by causing contact irritation or dehydration in the spiders, which ultimately makes them want to stay away from treated areas.

There are a few things you can do to keep spiders out of your house. One is to remove clutter, as spiders like to hide in dark, cluttered spaces. You can also use spider traps or pesticides to get rid of them. Finally, you can seal up any cracks or openings in your home so they can't enter.
