No, mothballs do not keep bats away. Not only are mothballs completely ineffective when repelling or removing bats, but using them could be illegal, depending on where you live. Remember, bats are federally protected, and it's illegal to use chemicals during the removal process, and mothballs tend to fall into this category.

Anecdotal evidence suggests coffee grounds can keep chipmunks away. Sprinkle them throughout your garden, yard, and plants to help deter them. As an added bonus, coffee grounds can help keep the slugs away, and they’re great for acid-loving plants such as hydrangeas, azaleas, and rhododendrons.

Whether you, your dog, or your cat has been sprayed, Poison Control recommends using a solution of 1 quart of 3% (household strength) hydrogen peroxide, ¼ cup of baking soda, and 1 teaspoonful of liquid dish detergent mixed together and immediately applied to the sprayed fur or skin to get rid of skunk smell. After leaving it on for five minutes, rinse with water. If your eyes get sprayed, rinse for at least 15 minutes with room-temperature water.

Most spiders are harmless and are more interested in finding and eating insects than trying to bite you or your family members. Certain spiders in your home may be advantageous if you have an issue with insects. Most spiders are non-venomous and have small mouths, so even if they did bite you, it wouldn’t be enough to cause any harm.

However, some species of spiders can cause harm if you are a victim of their spider bite, including the black widow and brown recluse varieties. Both species’ venom is poisonous, and you should seek medical help if bitten.
