Bee Invasion?!

Two days ago, a swarm of bees 'invaded' my dad's beloved giant bougainvillea or pokok bunga kertas. There were about few hundreds of bees surrounded one of the tree branches in an attempt to make a beehive around it. At first my dad didn't noticed it, not until they stung my dad a few times. When I went out to check it out, it surprised me that the amount of bees surrounding the branch. To eliminate it, we use mosquito sprays and most of the bees died, but some managed to escape.

After that incident, my dad joked with my neighbour that we might enjoy some free honey if we did not eliminate the bees :P
