Yikes! Those sound like Africanized Bees, don’t they? They are so dangerous, and I do hope you get someone to take care of them right away. :(
Yes - they are africanized - according to the pest control expert. The tree by my front door is dripping sap (woodpeckers) - so it is a pretty complicated problem.
The bees are foraging for food, and as there are no flowers this time of year, they are going for the sap. The woodpecker is pecking into the tree, because it has bugs in it. So, I need to have three companies work on the problem - a Bee Keeper, Pest Control and an Arborist (to save the tree.)
