Simply fit the funnels into the side of a 1- or 2-litre plastic soft drink bottle (that you supply) by cutting two slits for each funnel and inserting. Add homemade attractant liquid (recipe included) to lure wasps/hornets to crawl through the funnel and become trapped inside the bottle.
Ideal for use at picnics or barbecues.
