Roaches have a strong sense of smell and are repelled by a variety of potent aromas. Scents that can help deter them include citrus (such as lemon and orange), herbs like peppermint, mint, basil, thyme, and oregano, spices like bay leaves, cinnamon, clove, and garlic, as well as lavender, eucalyptus, citronella, tea tree oil, and vinegar.

You can use these scents in several ways to create an unwelcoming environment for roaches:

• Plants: Place mint or lavender plants in your home or garden.

• Powders and Leaves: Sprinkle garlic powder or place crushed bay leaves and citrus peels in high-risk areas like kitchens, bathrooms, and entry points.

• Sprays: Create a diluted solution with scents like lemon or vinegar to spray in your home. These can also be used in cleaning products or as room fresheners.

• Essential Oils: While essential oils of these scents can be used, be cautious as they can be toxic to pets if inhaled.

It is important to note that while these smells can help keep roaches away, they typically do not kill them and may not be enough to drive out an existing infestation entirely. For best results, combine these scent-based deterrents with regular cleaning. Be sure to clean up all food spills, crumbs, and dirty dishes promptly, and keep trash cans covered with a tight-fitting lid to remove potential food sources.

Silverfish can infest a bed, but it’s not likely unless you have a major infestation. Silverfish may be attracted to the fabric of the bed and the dark corners of the mattress, so you should check your bed thoroughly if you are seeing silverfish throughout the house. Seeing them in bed is a bad sign, because it means they are eating your cotton or silk sheets while they’re there.

If you spot a wasp nest on your property, call a professional exterminator as quickly as possible. The longer you wait to call a pro to remove the wasps, the more you risk a painful sting. The concern is elevated if you or any family members are allergic to wasps or bees—the sooner you remove the threat, the better.

Scorpions can be drawn to your home for a number of reasons, and it depends on the type of scorpion you’re finding. Often, scorpions check out moist areas that attract their prey, including insects like cockroaches, crickets, and moths. If you’re looking for scorpion hotbeds in your home, start with cold and damp places like crawl spaces, attics, or behind appliances.
