How to make sticky insect trap glue


I am planning to place sticky covers to trap sucking insects and opted to use yellow and blue colour plastic covers which r readily available in mkt.

what i should use as gum on that covers to attract pest??


yellow sticky papers are readily available.

If you want to try your own, try coating a layer castor oil on the colored sheets.

you can also keep pheromone traps.

Can anyone suggest ideas of making phermone traps?
