The africanized bees are no joke. I found some in a tree a while back that would sting me just by getting too close (<10ft) to the hive. I tried my best to not bother them but just mowing the lawn I had to use a full bee suit to avoid being attacked/stung multiple times. I live in the city so I got rid of them because they were so agressive and the tree was right near the road where people would walk by and could easily be stung.
