1) Use a reusable pail or bucket for trick/treating (my kids use the same buckets for Easter egg hunting and other events throughout the year).
2) Don't water your lawn today (your grass will survive and the neighborhood kids will appreciate walking through your dry lawn to your front door).
3) Consider going trick/treating earlier (before it gets too dark), you will be able to cover more houses and conserve energy from limiting the use of flashlights.
4) Wear reusable reflective gear on top of your Halloween costumes.
5) Avoid purchasing single use items (avoid buying glow sticks) and use flashlights instead.
6) Consider donating your extra candy to a local women's/children's shelter.
7) Have your kids reuse old Halloween costumes. If your kids have outgrown old Halloween costumes, donate them to friends, family members or the local salvation army.
8) The following are healthy alternatives to candy: stickers, erasers, pencils, and other school supplies. Avoid giving away disposable plastic toys (that are poorly made and non-recylcable).
9) Consider giving away discount coupons to local entertainment activities to support local stores and businesses (we received a discount coupon to a local bowling alley before and it was the most thoughtful Halloween treat).
10) Do not litter. Make sure kids place candy wrappers and other holiday trash where they belong.
11) Do not discard your carved pumpkins. Instead, include the pumpkins in your compost bin. If you do not have a compost bin, ask a neighbor who has one if he/she would like to include your pumpkins in their compost.
12) Use leaves to decorate your homes (instead of plastic decorations). If you do use plastic decorations, remember to store them in clearly marked Halloween bins so that you can easily reuse them next year.
