Rats are attracted to homes that provide food, water, and shelter. Common attractants include uncovered garbage, pet food left out overnight, crumbs and food spills, and easily accessible pantries. They’re also lured in by leaky pipes, standing water, and cluttered areas like basements or garages. Outdoor factors such as overgrown vegetation or woodpiles near the foundation can create additional nesting opportunities.

One way to keep pests away is with good housekeeping. Keep ants away with a clean kitchen. They’re less likely to wander in looking to score some free food if there isn’t a mess to find. Wipe down counters, don’t leave dirty dishes around, and keep food in air-tight containers. 

Home and yard maintenance can also keep pests away. Seal windows, patch any holes or cracks, and put screens on the vents to prevent bugs, rodents, and other uninvited guests from coming in.

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.

Carpenter ants don’t eat wood. It’s a common misconception because many kinds of termites eat wood as well as live inside it. Carpenter ants, however, are omnivores and only chew into wood to create pathways and nests, discarding the chewed wood as frass which is a major indicator of a carpenter ant problem. They prefer to eat smaller insects, sweet things like spilled honey, and sources of protein like pet food.
