Squirrels hate not having access to secure shelter or food sources. Your best line of defense is to make your property less attractive by removing access to these things. There are chemical squirrel repellents, but these have mixed success. According to Pennsylvania State University, you can apply products containing the bittering agent denatonium saccharide to a squirrel's favorite fence, tree, or roof spots. However, you need to reapply repellents regularly, which aren’t scientifically proven effective.

Rats are nocturnal creatures, meaning they are most active at night, typically from late evening through the early morning. They use the cover of darkness to explore, forage for food, and find water, as they feel safer and can avoid daytime predators and human activity. Their sharp senses, including keen night vision and hearing, are well-suited for navigating in the dark. Because they prefer to stay hidden during the day in secluded areas like walls or attics, you are more likely to spot signs of their presence—such as droppings or gnaw marks—before you see an actual rat.

There are plenty of scents spiders hate, but there are some scents scientists believe can work in the opposite way and attract them into your home. Some studies suggest that spiders may be attracted to stinky items like smelly socks. One thought is spiders are attracted to smells that attract more insects, such as mosquitos, which they feed on.

It’s debatable, but most will say either termites or bed bugs are the hardest to remove. When dealing with termites, you must find the central nest (as opposed to satellite nests) and exterminate the queen and all potential queens, which often takes the work of a specialist. Bed bugs, meanwhile, are incredibly hardy, good at hiding, and resistant to pesticides, so it takes very careful, very thorough work to get rid of them permanently.
