Take a piece of cardboard 220 × 150 (mm).

The most important part of the capture box is the capture surface. Take a piece of plastic film, cut it to the same size as the bottom of the box, apply adhesive and lay it on the bottom of the box. Cockroaches can be caught, the key lies in the adhesive. Adhesive has two functions: one is to introduce cockroaches into the box, and the other is to stick them on the catching surface. Modulation of the lure agent: mix 40% meat powder, 50% flour, 10% soybean cake, the total amount of about 20 grams, mix well and wait for use. Adhesive is 20 grams of rosin mixed with 10 grams of vegetable oil, heated to a gelatinous state, the lure and the adhesive mixed and stirred well, that is, made of adhesive.

To mix the above paste evenly coated in the plastic film has been lined with the capture surface, and then folded inward according to the original drawing of the dotted line, and finally the tongue b inserted in the notch a.
