How to make a Pitfall Trap
This is a good way to study the ground-crawling bugs that live in your garden. Insects fall in and they can’t get back out, so make sure you check your trap every day.
1 Cut the top third off a plastic drink bottle and place it upside down on top of the bottom half.
2 Dig a hole in the vege garden or flowerbed and set the trap so that the top rim is flat with the soil, so the bugs crawl in.
3 To protect it from rain or sun place a lid over your trap. Sit it on some stones with gaps in between so the bugs can still get through.
4 Leave your trap a few hours (or overnight) and then look to see what you have caught. You could do it a few days in a row or in different places (e.g. in sun and shade, damp places or near old logs) to find out where the most bugs live at your place.
