The chemicals we apply are registered to be used in hospitals, schools and public places. They need to be used in conjunction with protective clothing, especially when mixing. During application we recommend staying indoors and if possible, especially if you have young children or could be pregnant, to leave the house while treatment is in progress.
As a precaution we recommend yes, take any asthmatic children away from the house during spraying/injecting.
We normally only spray the skirting boards inside the house, which is not where babies crawl. However as a precaution we ask you keep babies away from areas in which we have sprayed for several hours until the chemical has dried.
