<human>:  How can I protect my home from pests without using harsh chemicals?
<bot>: One way to protect your home from pests without using harsh chemicals is to seal up any cracks in walls or windows, keep food and garbage stored away in airtight containers, and vacuum often to remove any crumbs that could attract pests. Additionally, you can use natural deterrents such as diatomaceous earth or essential oils to keep pests away without the use of harsh chemicals.
