The smell of the chemicals permeated the house for over a day. We blocked off and had to stay upstairs. It was absolutely horrible! Even outside of the house had very, very strong chemical odor after 12 hours. There is definitely a problem with either use of a new chemical or very serious over application. I called Paramont and was told there were no change in the chemicals used. Yesterday I read that deltamethine was used. I do not have access to previous reports to compare with. My wife is very, very upset and would appreciate a call from management with an explanation 540-822-5092.
