Heat is the most effective instant killer of bed bugs. Exposing them to temperatures above 131 degrees Fahrenheit for over an hour can eliminate them. Methods like steam cleaners and using a dryer on high heat are effective for this. Other options that can kill bed bugs on contact include EPA-approved pesticides, bleach, disinfectant sprays with alcohol, diatomaceous earth, and hydrogen peroxide. While freezing can work, it is not an instant solution, as it can take several days at 0 degrees Fahrenheit to be effective. Keep in mind that many DIY treatments won't reach bed bugs hidden in cracks or behind walls. For severe infestations or the most effective results, it is best to hire a professional exterminator for a professional heat or chemical treatment.

There are quite a few opinions regarding using coffee grinds to keep deer out of your garden, with many people convinced of this method. It makes sense that it could work considering deer have a strong sense of smell and likely do not like the smell of coffee grounds. However, there’s no hard evidence supporting the notion that coffee grounds keep deer away, but it may be worth trying.

The cost to hire a pest control specialist varies depending on the type of infestation. For example, the cost to exterminate spiders averages from $100 to $300. Other pest control costs include:

• Ants: $100–$500

• Bed bugs: $350–$5,000

• Cockroaches: $100–$600

• Fleas: $150–$400

• Rodents: $180–$600

• Wasps: $100–$1,300

• Mosquitos: $70–$500

• Bats: $230–$700

• Beehives: $75–$1,500

• Termites: $230–$2,500

• Snakes: $130–$600

• Armadillos: $50–$500

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.
