About Our Traps
Bait traps are used to capture Lepidoptera attracted to fermenting fruit, faeces, and rotting meat. Our traps are based on the tried and tested Van Someren-Rydon style and take into account scientific research on effective trap design. They are lightweight and pack down to a slim size, and have a number of features designed to improve performance and ease of use.
A 36cm (14") landing platform made of easy to clean semi-rigid pvc is used for our traps. The gap between the cylinder and platform can be easily adjusted from 2cm (3/4") to up to 13cm (5") using sliding cord-locks, so you don't have to struggle with knots.
Four hanging points provide secure positioning. The main netting cylinder is washable, with no internal projecting seams, and is fitted with a full length vertical entry double-slider side zip for easy access to the butterflies and for the removal of unwanted insects. A removable clear colourless PVC cover which protects the top section of the trap from rain is also available.
Finally, to trap lower-flying species or where there is no available hanging point, our 'hang-it' frame may be used. Made of fibreglass rods, this frame is quick and easy to assemble.
A Simple Bait Recipe to Attract Butterflies:
2-3 very over-ripe bananas (or other over-ripe fruit to a similar quantity)
3.5oz (100g) white sugar
1/2 can of beer
1/2 crushed brewer's yeast tablet (optional)
2 pint container with lid
Mash or coarsely blend the fruit with the sugar, and pour into the 2 pint container. Add the beer (and yeast if using), and enough additional water to make up to the 2 pint quantity. Mix well. Place the lid loosely on the jar - it should begin to ferment, so do not place on too tightly or the container may explode!
The bait is now finished. It can be used straight away, or kept at room temperature and stored for a few weeks. To use, pour a small amount into a plant saucer or shallow bowl (with or without a small amount of chopped additional over-ripe fruit) and place where you wish.
