Pestrol Professional prides itself on using only Australian ingredient for the active ingredient: Natural Pyrethrins from Tasmania
1 x Pestrol Ultra refill will last you 4-6 weeks on average. Much longer if you choose to use only day time or night time settings.
Pestrol Ultra refills includes Natural Pyrethrins; whilst other cheaper refills can often include cheaper synthetic pyrethrins and pyrethroids as well as other chemicals.
Choose carefully and notice the pest repelling difference when you chose Pestrol. Chemically copied formulations are not as effective. Insects soon gain tolerances to synthetic formulas. Mother nature is very smart and every year the flower changes enough to keep the insects on their toes and out of your home or work place.
1 x Pestrol Ultra refill is 150g and will fit the Pestrol Ultra dispenser. (Can also fit the Morten and Expra insect automatic dispensers)
If you purchase the Pestrol Ultra Refills in larger packs you will save considerably on the overall per can price.
Pyrethrum is also the name of a natural insecticide made from the dried flower heads of Chrysanthemum cinerariifolium and Chrysanthemum coccineum.
