Hello again Seetaram,
Thank you for your response. And here i also wnatto Thank god you know why , I just discovered it is not a bee hive it is called hornet itseems. and the pest control guy mentioned it can be removed by a kind of a spray from 15 ft they are may be about 4 or 5 of them living in that hornet not sure if they are bees or wasp or what kind but they did sting me for sure. but good part is they are not honey bee hive Now is it also bad ....? that I still don\'t know.
