Things You'll Need
Several old CD's or DVD's
Though blue jays are beautiful birds and can be fun to watch, but they aren't always the best birds to have around the house and yard. Blue jays can be extremely aggressive, especially when they have young chicks, and can dive bomb you, your kids and your pets. They can also be loud and poop in and around your lawn or garden. You can scare blue jays away without hurting them or them hurting you.
Use your scissors to cut several pieces of string about six to eight inches long.
Tie one piece of string to each old CD or DVD by threading the string through the center hole. Tie it at the top of the CD. You should have about four to six inches of string left at the top of the disc. Use it to hang the CDs from tree branches.
Tie several CDs or DVDs to tree branches where the blue jays gather.
Do not tie the CD's too close to one another. The discs should be several feet apart.
Turn the CDs or DVD' to face outward, so that the shinier of the two sides catches the sunlight. Depending on the time of day, you may have to turn them another direction to catch the sunlight and repel the birds.
