This product has worked really well and with the bait we have use ( berry jam and a little water ) reduced the number of wasps in the apiary. works for me and because it uses a plastic water bottle for the bait chamber helps the environment too
Extremely effective trap
No instructions referring to what gap to employ
Neat idea offered at a reasonable price. It also re-uses plastic bottles, so a winner all round. We probably won't know if it is really any good until we have been overrun with Asian Hornets, but in the meantime, it's the trap we will be buying. Good service, quick delivery. Good price.
Goods arrived on time as promissed and in good condition.
