1. Use glow sticks. This is especially important if your costume is dark, which can make it difficult for drivers to see you at night. Glow sticks are cheap and can be found in dollar stores and in the Halloween section of most other stores.
2. Don't enter a stranger's house. This should be a no-brainer, but I figured I should mention it anyway. If anyone invites you or your child into their house to receive candy, and you don't know them, do NOT go in.
3. Don't let children trick-or-treat unsupervised. Kids should not be walking around alone at night anytime of year, but on Halloween it is especially important. You never know what kind of weirdos are walking around watching these kids.
4. Don't accept unpackaged candy from strangers. If you're at the house of someone you don't know, and they give you an uunsealed/unpackaged/homemade treat, don't eat it. I hate to sound paranoid, but you really never know what people put in these treats. There are a lot of sick people out there.
