Tell your neighbour that you have to go out for the day but you are expecting an extremely important delivery. Tell them that they must look out for it as it could arrive at any moment of the day.
Hopefully your neighbours will spend all day staring out their window waiting for this extremely important life or death type delivery which never comes.
might as well....and tell them that you have black widow's also..lol..that also escaped....just tell them that they don't have anything to worry about if they don't have pets.
