Groundhogs have a strong aversion to powerful scents, including garlic, ammonia, vinegar, hot peppers like cayenne, and predator urine. Various herbs such as rosemary, lavender, basil, mint, sage, thyme, and oregano can also act as deterrents. You can strategically use these odors around your property by planting these crops near your garden and by the entrances to groundhog burrows. Commercially available repellents offer another option, and for best results, scent-based deterrents should be used alongside other preventive measures.

Water bugs won’t actively chase you, but they earned the nickname “toe-biters” for good reason. Water bugs are highly defensive. They typically rest an inch or so below water, waiting for prey. But if they feel threatened by a human that gets close, they may inject the person with a harmless venom from their legs, which may feel like a bite.

Aside from incorporating smells that roaches hate in your bedroom, such as citronella, lemongrass, or clove oil, there are a few ways you can keep roaches away at night. First, try moving your bed away from the wall, as roaches will often climb the walls and onto your bed. If you’re still having trouble, you can also purchase a mosquito tent for your bed, or hang netting from the ceiling to surround your sleeping area. Make sure it isn’t touching the ground, though, as they may attempt to climb it.

Most bugs that get into and reside inside our homes are harmless. However, you should address the presence of harmful ones, such as bed bugs, roaches, or termites, that can harm you and your home. Additionally, if you notice a significant increase in bug sightings of any kind, it's a good time to perform a home inspection, looking for water or structural damage that could be inviting them in.
