Block Flies with Basil
Flies hate the smell of basil. To discourage them, place pots of basil at doorways and windowsills and on the kitchen counter. Don’t have enough sun for potted basil? Put dried basil in a small muslin pouch, rubbing it occasionally to keep the scent strong.
Scare Off Spiders with Citrus
Spiders are not fond of citrus. In a spray bottle, mix water and unsweetened lemon or lime juice. Wipe your countertops with the mixture or spray down doorways and windowsills. You can deter spiders in your garden by spreading around lemon, orange, or lime peels.
Avoid Ants with Vinegar
Use a 50/50 solution of vinegar and water to wipe down countertops and other surfaces—anywhere you’ve spotted ants. For best results, repeat this several times a day. Doing so destroys the scent trails that ants use to navigate.
Fake Out Wasps with a Fake Nest
Wasps are incredibly territorial and will not build a nest within 20 yards of another one. So build or buy your own fake nest! It’s like a scarecrow for wasps. Hang one in the front yard and one in the back, and you’re done.
Combat Mosquitos with Catnip
Cats love it. Mosquitoes? Not so much.
Repel Fleas with Salt
Alternately salting and vacuuming your ﬂoors will kill ﬂea eggs. But since fleas have a three-day reproduction cycle, you have to be diligent: Salt every day for nine days and vacuum every third day. Don’t forget to empty the vacuum every time, or the live ones will crawl right back out again!
Eliminate Fruit Flies with a Deadly Recipe
How to make the deadly mixture: Fill a glass three-quarters full with vinegar or cider vinegar, then add six to eight drops of dishwashing liquid, and fill to the top with warm water. Watch them drop like flies 🙂
Deter Deer with Irish Spring
Hang Irish spring soap or spike it to a stake near things that deer like to eat. Or you can sprinkle shavings or small chunks on the ground.
