Re: semi-OT: deterring critters in the obsy

Peter Nagy

I don't have an observatory but every Spring maybe in April, if I see wasp trying to build a nest in my backyard, I use a fly swatter to wack as many wasps as I can and at least one of them is a queen, they never seem to swarm my yard again until next year. It's usually no more than 10 wasps a year to wack them.
