Parenting Question

So, Joshua saw a bee last Saturday in the backyard and now he is petrified. He's loosing his mind about bees!!! He's wearing long sleeve shirts everyday, he's covering up with his towel to go in the pool and he's talking about bees and what they do, why they sting, etc. every day since. I basically want to yell at him - which isn't a great parenting technique. Any advice on how to handle a 5 year old who doesn't want to go outside because there "might be a bee out there"? Summer should be fun if he keeps it up!

Hamster Update

Just wanted to let everyone know that hamster #3 or "Blackie" is alive
and well and keeping us up at night. She's a crazy busy hamster who
spends most of her waking hours trying to chew out of her cage and
running in her wheel. Anyway, besides the fact that she's irritating
we're glad she's alive and well - I don't think Joshua could handle
purchasing a 4th hamster in 2 weeks.
