Not 100% efficient, but they do work !
Ok, i was very skeptical at first, but they do work, I used one with the cheapest coke I could buy and another with just sugar water - both caught Wasps, the coke been the best solution I used, but I did notice a few got away too - so not a true 100% catch rate, but good enough to substantiate the initial purchase and naturally use again when the weather improves. Not unsightly either lightweight and worth while trying yourself if you get invaded by the little bleeders like we did this year !
