I'm trying to find the top 12 worst criminals, animal pests, bug pests, and types of litter in cities/towns/villages and in what order their severity would be. So, top 12 types of criminals, top 12 animal pests, top 12 bug pests, and top 12 types of litter. I'd do a poll, but that wouldn't be adequate. Please either tell me some of what you consider the worst, put them in a 1-12 order, suggest others not on the list, or even suggest what should be eliminated from the list because it is too similar to another. This is for a game I'm making. I'm going to make 12 "cards" for each category on which I'll write these on and give them a severity rating from 1-12. Each player will have one of each category and will try to exchange their cards with other players and the person with the lowest combined score wins after 3 swaps.

Here's what I have thought of to choose from:

Criminals:
kidnappers
arsonists
drug dealers
armed robbers
con artists
counterfeiters
deadbeat dads (not criminal, but hey)
vandals
stalkers
auto thieves

(I don't want to include murderers and rapists and pedophiles and such as would bother the people and/or their parents playing)

Animals:

rats
stray cats
stray dogs
raccoons
bears
foxes
weasels

squirrels
opossums
scorpions

Bugs:
ants
bed bugs

cockroaches

beetles
moths
slugs
bees
fleas
hornets
centipedes

silverfish
termites
wasps

Litter:
