I remember all the "hype" a few years back about Killer African Bees and it was scary. It would indeed be frightening to be attacked by aggressive bees or wasps or hordes of any insects and I think many folks do grab the pesticide first out of fear! With conflicting reports, it's also confusing to know the proper thing to do regarding the Africanized bees. It says here that the Florida Dept. of Agriculture and Consumer Services recommends that all wild bee hives be exterminated.

I read that rather than aggressive, the Africanized Bees are just defensive of their hives but it is scary because this article states that they will chase a human or animal for a mile!!

Not knowing one bee from another, if I ever find a beehive on my property I won't call an exterminator but I'd definitely call a beekeeper to come check it out and hopefully remove it.
