In this idea, We present to you the ways to make Halloween safe during COVID. To do this idea , we will answer these questions:
How to deceive or treat safely?
How to give candy?
How to do activities at home?
How to have fun safely in the community?

The steps:-

Set ground rules for trick-or-treating to make it as safe as possible. Wear a face mask when you go trick-or-treating. Go trick-or-treating in small groups. Practice social distancing as you trick-or-treat. Sanitize your hands often. Wipe down candy and Halloween goodies just to be safe. Encourage children to wash their hands before eating any candy. Invite neighbors to drop candy on your doorstep as an alternative to traditional trick-or-treating. Place your candy in goodie bags so each child gets their own treat. Hang pieces of candy along your fence so kids aren't coming up to your door. Wear a face covering if you give out candy door-to-door. Avoid using large candy bowls. Hang up festive decorations around your home. Make tasty, Halloween-themed treats at home. Carve and decorate pumpkins at home. Hide candy around your home for a fun scavenger hunt. Turn your home into a haunted house for your kids. Host a costume party over video chat. Plan a Halloween-themed movie night with your family. Search for drive-through, Halloween-themed activities in your community. Distance your cars by 6 ft (1.8 m) for trunk-or-treat events. Take part in a "haunted forest" instead of a "haunted house." Host a socially distanced costume parade with your neighborhood. Use hand sanitizer before going apple or pumpkin picking.

The details:-

Let your children know that things are going to be a little different this year and that they should be extra careful when they're grabbing candy. Remind your kids to put on a mask or face covering before hitting the streets. Limit the trick-or-treating group to 3-4 kids total, so your child will have a lower risk of passing or catching germs. Whenever possible, encourage your children to stay at least 6 ft (1.8 m) from the other families trick-or-treating, which will help prevent the spread of germs. Remind them to keep their hands clean throughout the night, since they'll probably be touching a lot of surfaces. Sanitize your child's candy with a cleaning wipe and let it air out before they chow down. Remind your kids to wash their hands with soap and warm water for at least 20 seconds, which will get rid of any germs. Talk with your neighbors about dropping off baggies of candy at everyone's homes instead of having your kids go door-to-door. You can also place these baggies along the edge of your driveway or porch, so you don't have to have any face-to-face contact with the neighbors. Consider packing non-edible treats in baggies, in case any neighborhood kids have food allergies. Wash your hands between each trick-or-treater visit, and make sure that the neighborhood kids stay on your porch and don't enter your home. Big bowls hold a bigger risk for spreading germs, especially if the neighborhood kids have some trouble deciding which kinds of candy they want. For a fun twist on classic Halloween decorations, go through some old family photos and hang up some pictures of your old Halloween costumes on the walls of your home. If you have really young kids at home, check that your treats don't have any choking hazards. Help your young kids carve their pumpkins, or supervise your older children as they carve out their design. Look for fun, creative places around your home where you can hide treats for your young ones to find. Invite your kids to help decorate your home to the nines with spooky decorations, like carved pumpkins and ghosts made from pillowcases. Arrange a big video chat or Zoom call with your children and their friends. Make a plan to watch a bunch of Halloween movies together, where everyone dresses up as their favorite spooky character. Focus on activities that are held outdoors, where you and your family can safely social distance while still having a good time. Check that your car is parked a safe distance away from the other vehicles in the parking lot, so there won't be as many germs spread around. Look for a "haunted forest" that's being held in your community—this is essentially the same thing as a haunted house, but outdoors and in a larger area. Talk to your neighbors about hosting a costume parade on the weekend, where all the neighborhood kids can show off their Halloween costumes. Try to stay distanced from other people in the area, and sanitize your hands whenever you pick out some apples or pumpkins.
