Pestrol Dispenser automatically sprays a microburst of insecticide every 5 minutes. Large cans last for approx 5 weeks. Natural pyrythrin technology keeps away flies, crawling insects and other nasties.  Safe for use in kitchens and restaurants. These have taken the plae of the older Robocan dispensers and refills.

Cans screw into the dispensing head - CANNOT be used as a stand alone aerosol insecticide.
