Brown recluse spiders are attracted to homes and properties in search of shelter and food. Key attractants include a steady supply of insects, which are their primary food source. Consequently, things that attract other bugs, like food left out or poorly sealed trash cans, will also indirectly attract spiders. They also seek warm, dry, dark spots with nooks and crannies for nesting, such as untended wood piles, dirt piles, and cardboard boxes. Additionally, excessive outdoor lighting can attract insects, which in turn draws in spiders.

Yes. German cockroaches are masters at hiding. If you notice one cockroach, especially in daytime hours, it’s very likely that other roaches aren’t far behind, or that the problem is growing.

Squirrels have a strong sense of smell and can be deterred by various scents they dislike. Effective options include peppermint oil, rosemary, garlic, cinnamon, white vinegar, coffee grounds, and predator urine. Squirrels also have a strong aversion to capsaicin, the compound that makes chili peppers hot, making capsaicin-based repellents a good choice for protecting specific areas like gardens or bird feeders. For a DIY solution, you can create a garlic and vinegar spray and apply it daily. Additionally, placing strong-smelling items like certain soaps or dryer sheets near where squirrels frequent can also be effective.
