Paper wasps, like many other wasps, are attracted to sweet smells that remind them of nectar. That’s why wasps may buzz around you as you snack on watermelon on the patio. They may also like the scent of certain perfumes. Standing water attracts these wasps, too.

Paper wasps are also attracted to warm, sheltered spaces, where they can build nests and raise larva in protected areas away from predators. They may also be attracted to untreated wood on your deck or fence, as they use wood pulp to build nests.

Voles are pretty prolific breeders, managing to squeeze in 5 to 10 litters a year, and each litter usually has around 3 to 5 little ones. These furry creatures are flexible with their love lives, as they can breed all year round, though spring and summer are their prime times. If they're living it up in warmer areas, voles don't take a break and keep reproducing non-stop.

A single bed bug bites multiple times throughout one night until full, but then takes a break for a week or so to digest. However, the more bugs present, the more likely you get bit every night. Tracking how often you get bit is a good way to approximate the size of the infestation.

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.
