Halloween // Any tips on preventing teenagers from trashing/stealing your candy bowl???

Every year there’s a decent amount kids in my neighborhood and obviously I like to leave out a cute little display and bucket or bowl of candy. Now my husband and I usually throw a halloween party so although I can check on it once in a while, it usually goes unmonitored most of the night. The last 3 years teenagers (i’m assuming) have completely trashed it and stolen all candy within the first hour or two. I’ve tried signs (which only seem to make it worse) and zip typing the bucket to the railing but never the less my bucket of halloween candy is taken away never to be seen again…

Any tips on how to deal with these hooligans or what y’all do to prevent premature candy theft?
