Can I just talk to you right now and tell you I am the mom who is gonna pull you aside & tell you bobbing for apples is a health hazard? Ya never know what the kids might have, cootie-wise. This is a diff time...much more dangerous spit. Call me weird, but I will pay you a nickel if a mom tells you this.
They could lash together (with twine) creepy tree decorations like the ones from Blair Witch.
.....tie a holed donut (PLAIN, not pwodered..trust me..it will ALL OVER the floor)with a string, which is tied to a fishing pole. Eater put hands behind back & other person holds donut pole...try to eat all the donut. Still germy, but not so much...could change string between players, or use a fishing clippie thing (word??) to switch out the strings to each indiv. donut.
Buy some plastic cheap pumpkin ToT buckets, number them and have kids toss bean bags into them for prizes/candy. Make bean bags out of old socks cut down & filled with rice..tie tightly with string.
Photocopy those fortune teller things that are made out of paper....yes, even boys like them. Have them color & cut out.

You can kill time by having a cake/cupcakes, too. Mixit up with games, activities, food. Older kids run games, younger play. Give out cheap treats/prizes like smarties or dum dums lolliopops.
Best event closer: pre-event, blow up a gazillion dollar store balloons (dont get long ones- too hard to inflate). Fill garbage bags with them. At end of party, dump all bags on floor at once & everyone has to SIT on them (NO hands or feet!) and break them...every piece has to be picked up afterwards.
Pool noodle sword fights...
Pin the Head on the Horseman....
Wrap 6, 1/2 gallon milk containers in orange tissue or spray paint...draw pumpkin face on each..or use 6 gallon plastic milk jugs & draw ghost face on them. Stack up pyramid style (3,2,1) and have kids throw bean bag to knock them over. (I like using bean bags as they dont bounce all over hi Hell....)
They can carve "shrunken heads" from apples....use plastic knives and have an example out and a vat of salt & lemon juice to pop them in to for a few minutes when done carving....pop the apple in a plastic sandwich bag with their name on it...have them take it home & put it in a 200 degree oven **with the door open** for several hours. Might want to post an instructional sign with pics for this one, and have drying instructions printed up they can tape to the bag. When dry, poke in & glue whole clove eyes & rice teeth....
PINATA! Balloon, you mache in advance while watching tv, making sure to attach a loop to hang it from ...spray paint or tissue paper with orange to make a pumpkin & face....cut hole, pull out balloon..put in candy..tape hole shut. DOnt make it too stiff or it will never break (have a jackknife in your pocket for just such emergency). Voila!
If I think of more, will let you know.
