Poultry farmers with manure sheds know how annoying flies can be in summer. This fly problem, which until recently was almost uncontrollable, is caused when the fly larvae are not sufficiently controlled, which means that they still have the chance todevelop into flies. But the maggots can now be controlled by use of the new Mabes sprayer. By intervening at the time when maggots develop into flies, the fly problem can be reduced or even prevented. The unique quality of the Mabes sprayer is in the treatment of manure during grinding out. The spray nozzle is placed centrally above the last manure conveyor belt. The adjustable stainless steel stand is very sturdy and can easily be fixed in place. The spray unit has a 220 volt input which is transformed to a 12 volt operational voltage for safety reasons. The unit is supplied as standard with a 8 metre hose. The Mabes sprayer uses 50-60 litres per hour.
