When Our Sons Allergys Begin, It’s Time To Respray Dustroy!

We have found Dustroy to be very effective. When our son starts to cough and clear his throat again, I usually realise that 8 weeks have flown past and it’s time to spray again. When I do, the coughing and throat clearing quickly disappears again. We’re very happy with the product and will continue to use it. Sydney Birchall Feb 2013
