I have used traps for insects for over 50 years.
- Simple bottle trap uses a straight side jar or one with a shoulder. Lightly vaseline the inside 1-2" using real Vaseline which is very slippery and wipe it off making the glass inside neck and lip un walkable by any insect. Put some food/banana or water source in the bottom. Many insects are seeking moisture. If you want burying beetles and flies put a dead mouse in the bottom. Bury it up to its neck in the ground and put some bark or a board over it to screen it from rain. Check it daily.
- Moth bait made from molasses/brown sugar/stale beer/ mashed ripe banana is mixed into a thick cocktail and paint it on some trees along a well known path before dusk. Use a lantern and bring a wide mouth jar with you and patrol the path and shine your light on the the painted spots on the trees. All sorts of moths, ants, beetles and wild cockroaches (usually the flying males) will be feeding on the bait. You will find wild cockroaches, which are very delicate and beautiful, all the way up into Canada. Enjoy the evening walk and collect them with the wide mouth jar placed over them for closer examination. You may collect some of the underwing Moths viewable in Legion of Night
