Making an Asian Hornet Trap - our efforts


* A 2 litre plastic bottle - preferably ridged with slightly larger bottom
Plastic garden wire - 15cm and 30cm
* A 10cm square off-cut of epoxy coated (not loose woven) wire Varroa floor mesh (available from some beekeeping suppliers)
* A 15cm square off-cut of rigid black plastic sheet, e.g. Wickes surface protection sheet
* Piece of stiff card cut to the internal diameter of the bottle (just under 10cm)
* A sharp knife or scissors
* Sheet metal cutters
* A nail held with pliers and heated in a candle flame
* Pliers, stapler, fine marker pen



1. Make an incision with a sharp knife and neatly cut around both just above and below the lower ridge of the bottle with scissors. Once done, this will give a sleeve effect, allowing the middle of the bottle to freely slide into the bottom section of the bottle;
2. Next make a similar incision at the top ridge and cut neatly around just under the bottom of the ridge;
3. You should now have three sections; the base, a middle tube and the top of the bottle. Remove the bottle lid;
4. Next invert the coned top section into the middle tube, hold the bottle neck centrally and mark the cone around the top of the tube with a fine marker pen; 
5. Cut on this line to remove excess plastic and form a snug fitting cone
7. Cut a circle of card to fit inside the bottom section of the bottle. Place over the square of Varroa floor epoxy mesh and cut inward towards the card circle at either side of each corner of the mesh to give a 1112mm wide tab;
8. Fold up the tabs vertically at 90° firmly against the card. Turn over the mesh and using the card as a template, cut at a slight angle to remove the excess wire mesh and fold back the top 8mm (approx.) of the tab;


9. Seat the finished grid into the bottom section of the bottle and bend the tabs over the plastic to fix securely;
10. Slide the open end of the middle tube into the base so that it rests against the mesh;
11. Make two small diametrically opposed holes through both layers of plastic with a hot nail held with pliers about 6mm from the top of the base section. The seams of the bottle can be used as a guide. The short length of garden wire is pushed through the holes to keep the middle and lower section secured together;


12. Make another pair of holes diametrically opposed 6-8mm from the top of the funnel;


13. Bend the black plastic sheet in half and make a fold approx. 12mm along each edge. Make holes in the ridge about 40 mm from each end and 6-8 mm from the edge at the mid-point of the folded sections


14. Feed each end of the 300mm length of wire through the apex and fold over with pliers to link together;
15. The black cover is then attached to the bottle trap – rivets have been used here for convenience, but small nuts and bolts or other fixings could be used.
The completed monitoring trap is then ready for use. Fill with a suitable sweet bait to just below the level of the mesh and hang in a sheltered sunny position in the apiary.
