There is a company called Blackwater that has time on its hands.:rules:
Only joking - very bad taste
There is a powder that you can lay for them to take back and they will take it home and in theory it will destroy them.
Best advice is as someone else said don't leave any food or scraps out anywhere.It is a good precaution to even keep the sugar and coffee in the fridge.They don't like the cold.
