Put some honey on a saucer and then place it on a table or counter, or the floor. Most likely you will catch some flies if it is higher up and roaches if it is closer to the floor. You may also catch ants this way.
The easiest way to make a humane insect trap is to take a 2 liter bottle and cut it in half. Then you can insert the smaller spout into the bottom.
the insect is attracted into the trap, by sweet syrup substance and once inside when the fly trap closes. they are liquified and turned into a natural protein for the fly trap
The Venus Flytrap hunts by luring insects into the jaws of its trap. Inside the trap are glands that secrete nectar. This tricks the insect into thinking it has found a flower. The trap has small sensor hairs that are triggered by the moving insect. The sensor hairs triggering causes the trap to shut and trap the insect.
The leaf/trap will be closed. If the insect escaped, the trap will open again a few hours later.
tactic movement in the leaf lamina to trap the insect
The mouth.
A Venus flytrap is a carnivorous plant that catches prey by snapping its hinged trap shut when tiny hairs on its surface are triggered. When an insect lands on the trap and brushes against the hairs twice, the trap closes, sealing the insect inside and digesting it with enzymes. The plant gains nutrients from the insect to supplement its diet due to the nutrient-poor soil it grows in.
To make sure that the insects are contained within the trap, the edges of the leaves have finger-like ciliathat lace together when the leaves press shut. These long, hair-like projections make the plant look like it has spiny teeth; but the cilia are really only used to latch the trap shut.There is an upper limit to the size of insect that the trap can accommodate. At most, traps are about 1 inch long, and an insect ideally should be about one-third of this size. If an insect is too large, the trap will not be able to form a seal tight enough to keep bacteria and molds out. Once bacteria and mold have a way in, they can proliferate as they feast on the decomposing insect, and the leaves of the trap will succumb to the assault as well. The trap will turn black as the leaves rot, and the whole thing will eventually just drop off the plant.sources: howstuffworks.com http://science.howstuffworks.com/flowering-plants/venus-flytrap4.htm

get a box or container, dig a hole as deep and did as your container, then place the box in it this box has to be big enough to trap a bug and not let it escape the idea is to put food in the box and the bug will go to the food and fall in and not be able to get out also check trap daily
Bladderworts trap their prey when their trap is triggered by prey brushing up against small trigger hairs attached to the trap door. Once the trap is triggered, it will close sucking the prey and surrounding water into the trap.
Insect-eating plants produce sticky or slippery substances on their leaves to trap insects. Once trapped, these plants release digestive enzymes to break down and absorb nutrients from the insect's body.
