Insert the bulb base into the small hole. Take a section of wire-finding, peel off the wire skin at both ends, wrap one end around the lamp holder, and pierce a small hole at the other end from the side of the plastic cover. Put the plastic lid on the can. Check whether the light bulb and battery are in close contact. The disposable flashlight will be ready here.

8, homemade cockroach catching box

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

The most important part of the capture box is the capture surface. Take a piece of plastic film, cut it into the same size as the box bottom, coat it with adhesive and spread it on the box bottom. Whether cockroaches can be caught or not depends on the adhesive. The adhesive has two functions: one is to introduce cockroaches into the box, and the other is to stick them firmly on the catching surface. Preparation of attractant: Mix 40% meat powder, 50% flour and 10% bean cake, the total amount is about 20g, and mix well for later use. The adhesive is prepared by mixing 20g of rosin with10g of vegetable oil, heating until it is gelatinous, and mixing the attractant and the adhesive evenly.

Spread the prepared paste evenly on the catching surface lined with plastic film, then fold it inward according to the original dotted line, and finally insert the tongue piece B into the notch A.

Because the mixture of rosin and vegetable oil is not dry, the viscosity of the bait can be as long as one week. Place the catching box in the place where cockroaches haunt. Because the box is dark and has the bait that cockroaches like, cockroaches will climb into the box to fight for the bait and get stuck on it. When it is full, the paper box can be crushed and discarded, and the plastic film can be removed and replaced with the plastic film coated with bait, so that the box can be reused.

If the size of the catching box is enlarged and the composition of the adhesive is slightly adjusted, the paper mousetrap can be made by thickening the coating.
