we have a flea problem and have finally decided enough is enough and have the professionals coming in on Tuesday. Can anyone tell me what they do and what they will treat. I have been instructed to hoover the house in the morning and then they will come in the afternoon, treat the house whist we are out. Apparantly i cant then hoover for 2 weeks, is this right??? and how will i manage that with 2 children under 2.5yrs and a cat!
