These are the signs of bed bugs to look out for:

• Blood or rust-colored stains on mattresses, fabrics, or upholstery

• Dark spots of excrement that look like dots from a fine-tipped permanent marker

• Tiny eggshells and yellowish shed skins

Yes, rats will go near a sleeping human, especially if there is food or crumbs nearby. What’s worse, they may even bite humans while they are asleep. Common places for bites are exposed fingers, toes, hands, and faces. To minimize the risk of rats approaching you and your family members while they’re asleep, do not eat or leave accessible food packages in the bedroom.

While carpet beetles won’t bite you like bed bugs do, they still aren’t pests you’d want to find in your home. Carpet beetles in their larva stage can be voracious and cause a lot of damage as they eat through fabrics on furniture, clothing, bedding, rugs, and other materials. If you see carpet beetles, you’ll want to have an exterminator come by to assess the damage and control the infestation.

Scorpions are repelled by strong scents like lavender, cedar, peppermint, and cinnamon. Applying essential oils of these scents mixed with water around your home's perimeter and entry points can act as a mild, chemical-free deterrent. In addition to scents, scorpions also tend to avoid well-lit areas, preferring to hide in dark, cool, and damp places during the day. However, it's important to note that these methods are not fully effective on their own and should be combined with other preventative efforts, such as sealing any potential entryways into your home.
