Squirrels rely heavily on their sense of smell and are deterred by a variety of scents. Some of the most effective smells for repelling them include peppermint oil, coffee grounds, white vinegar, garlic, cinnamon, rosemary, and predator urine. They also have a strong aversion to capsaicin, the compound that makes chili peppers hot, making capsaicin-based sprays an effective repellent for areas like gardens or bird feeders. For a DIY solution, you can create a spray from garlic and vinegar and apply it daily. Additionally, squirrels dislike strong, fresh scents, so placing items like strong-smelling soaps or dryer sheets in areas they frequent can also help keep them away.

The average lifespan of a stink bug is about six to eight months, depending on species and environmental conditions. Their life cycle includes three stages: Egg, nymph, and adult. Eggs hatch in roughly five days to two weeks, followed by a four to six-week nymph stage where they grow and molt. Once fully matured, adult stink bugs focus on reproduction and can fly to new areas, often seeking refuge in homes in search of warmth.

Adult fleas can live from a few days to about two weeks without a host. If pets are not available, fleas may feed on rodents or people. While adult fleas need a blood source to survive, flea pupae can lie dormant for up to a year in optimal conditions. Therefore, cleaning and treating the infested area is essential to prevent pupae from surviving and hatching later.

Fleas are master hiders, so they’re always looking for safe spots. In addition to living directly on your pets, they’re likely to hide in bedding materials, not unlike the infamous bed bugs. They also like carpet and thick grass, for similar reasons. They’re more likely to hang around dirt and debris in general, which is why it’s important to keep the home clean.
