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.

To freeze bed bugs, they’ll need to be exposed to very low temperatures of 0 degrees Fahrenheit or lower for at least 4 days. You can use a remote thermostat to determine when the infested item reaches 0 degrees. Keep in mind that bed bug professionals have the high-quality tools and equipment needed to eradicate bugs using extreme cold, so it’s best to hire a pro for this method.

Other than blasting aphids away with your hose set to jet, insecticides offer the quickest way to kill aphids on contact. Protect other insects and critters by choosing a natural insecticide for your garden, which can be as effective as a synthetic one.

They’re a nuisance, but silverfish aren’t nearly as dangerous as other pests like cockroaches, mice, termites or bed bugs. They don’t carry diseases that humans or pets can catch, and they don’t cause widespread destruction like termites or rats. Silverfish are small and find it very easy to get inside any exposed foodstuffs. Like weevils, you may find them in unprotected flour, cereal, grains, bread boxes, chip packages and more. They will happily nibble fabric and paper as well, so they can cause damage to furniture, clothing, books, bedding, curtains and other materials.
