Asian Hornet Cone Trap by ANEL

I am pleased with my purchase but I wasn't sure whether the hole was too big. I read another review on this product which stated that it allowed bumble bees and the European hornet through, something I do try to avoid if I can. i cannot agree with that information yet as I haven't used it yet, but I feel it will be useful anyway to adapt if necessary to put a trap together and have tried using the red clearer cones inside to reduce the hole. I would definitely buy again as they are reasonable priced.

much larger than expected, good product, waiting to test this coming season

The entrance hole is too large and allows bycatch including European Hornet (Vespa Crabro), Bumblebees, some Moths etc.

I suggest glueing a cap from eg a sauce bottle and drilling with the correct size of drill 7.8mm is recommended for Vespa Velutina; 8.6mm admits Vespa Crabro.
So 8mm should be a suitable hole size.

The hole in the end is too big and will allow almost everything in including Bumblebees and European Hornets. There are rows of slots all down the length of the cone but these are too small to allow anything out. The actual cone is a hard brittle type plastic so I’m not sure you could drill in to it to secure it to anything like a box to make the trap. It’s going to take some working out as to how to make a trap with these. They were quite cheap so worth having a go with.

These are the best I have found so far, well made, easy to use and a great price, combined with a quick delivery
