Japanese Killer Bee or not killer Bee?

Do you think they were Japanese Killer Bees?

I had noticed whenever I open Net door to go to the balcony some very big bees started flying near door. I thought it could be by chance. But those bees were not normal they were very Big/Long that worried me. In short, one day I found out they had nest on the metal(a bracket used to hand cloth in Japan). In a protective way, I pushed that nest with a bar and that nest fell down on the floor.

Guess what? so many bees appeared out side of the (Net) door as they were angry at me. And many were coming out from the broken nest. From inside I used Bees killer spray but some did not die rather flew away. Next day they were still coming out of the nest so I used Bleach on the nest and forget them. After 3 weeks when today I wanted to take photos, some bees appeared from distance that is why I had taken very few photos.
Please take a look and inform me if they are Killer Bees? Do they remember if I am the one who messed with them?

Japanese Killer Bee

The killer bees are a blend of honey bee and African bee. Why would they be in Japan? The current problem we have here with killer bees was a result of some getting loose on our continent after a beekeeper had blended the two, the queen escaped.

Some how when I search for Japanese Bees the outcome will always be hornet bees.

I can't be sure to say that your bee is a killer bee. You should identify it with the tips above, but in any case be careful maybe get a pest control to get rid of it for you, so you won't end up in an accident and lose your life.

Killer bees wouldn't stand a chance, it doesn't matter the aggressiveness of the bees considering the fact that they are going to nonetheless find it complex to penetrate the armour of a tremendous hornet.
