Contact county and state poison control and ag departments. Also, call nearest hospital by initially getting the label and MSDS of the chemical used. Also, leave house and return after additional airation. If you have children thoroughly wash all plastic toys, chairs, table they touch. Also, discard whatever you can from what children will be touching instead of washing them. Check for plastic coverings on clothing and open them if they were not. If you have water beds, remove them and leave them outside for at least a week. If you have woodlooring or laminate flooring where children like to play, do steam washing by making sure not to apply any deodorants or anything other than completely natural aids such as vinegar. So called "green" cleaning sprayers are not completely natural, they may have some degree of natural ingredients but if you read the label it does not mention about other materials used.
