15. Get Rid of a Bee's or Hornet's Nest
Under the cover of darkness, when the stinging pests are all tucked into their hive, soak its entrance with a jet-spray insecticide from a safe 10 to 15 feet away. If the hive shows no activity the next day, discard it. For carpenter bees, spray each hole they've bored in your house, "and expect it to be an ongoing battle," says Tom Scollins, a longtime pest-control pro who's now at Baltimore County Animal Control. If you have honeybees, look for a local beekeeper who might come and take the nest so they can live to pollinate another day.
