The quoted time frame on the website is 2-4 hours but like you say if you have bees in the garden.No, you buy it once and then it is reusable as many times as you want. You recharge the pads by placing in boiling in water for 20 minutes. It takes 2-3 hours so I could do 2 hives a day for as long as I wanted. I agree it's probably aimed at the hobbyist with a few hives rather than the bee farmer.
I have 12 hives - I could treat them all twice a year for several years. Seems like over 3 years it would work out at less than £3 a treatment - reasonable?
If it works, whats not to like? It's chemical free, can be used at any time with no (apparent ill effects) and extremely quick.
I'm a Yorkshireman and a beekeeper - you'll have to find someone else to sell your magic beans to
The product info appears to indicate that it’s only used on a single brood with outside temps of 15c. I wonder how that affects 14x12 and certainly restricts those who operate dbl broods.
It be interesting to see how in real world or less than ideal circumstances it operates.
