A simple Asian Hornet trap

Following the excellent session by Nigel Semmence on the impending invasion of the Asian Hornet he indicated that the queens appear from February onwards and now was the time to prepare and set bait traps.

Not wishing to do the commercial boys out of a quick sale I set about constructing my own in true Blue Peters fashion but without any sticky backed tape. So here goes …

1. Take an empty two litre clear plastic bottle – coke, lemonade or other.

2. Leaving the outer wrapper on carefully use the upper edge as a guide and carefully cut or saw the upper portion off. 

3. Remove the outer wrapping.

4. Using that upper portion invert it into the lower portion which will give  a snug fit but if it starts to distort cut into the upper portion by about an inch and put the two portions together with the top edges flush.

5. You now have effectively a funnel, a trap into which hornets can easily get but more difficult to escape.

6. The diameter of the upper hole of this funnel will be about 90mm – 3½ inches in old money which you now need to protect from ingress by rain so you need to find another suitable plastic bowl or similar that can be inverted to form an umbrella but at the same time held clear of the trap by some means. A container of about 130mm – 5 inches seems to be fine.

7. Simple, use four clothes pegs set at 90 degrees around the trap giving sufficient height and clearance to allow access to the trap.

8. The trap now has some weight but dependent upon where it is to by placed may require some extra to compensate for excessive movement. The only other thing required is to affix some sort of hook to suspend it so it is expedient that both the umbrella lid and trap itself are joined together. For this I used a fine point soldering iron to pierce both parts and hooked through some galvanised wire to do just this and at the same time allowed for it to be suspended.

It now remains just to bait the trap (Nigel suggested fish but under no circumstances honey), to hang it up in trees or shrubs at a height of between 2 and 4 metres – 6 to 12 feet and to check it daily reporting any trapped hornets to the website This email address is being protected from spambots.
