I use the traps to catch flea beetles, but have seen some other bugs on them before. Mostly just fruit flies though, that I can remember.
What you will need:
~ Tree Tanglefoot
~ Florescent yellow paper
~ Sticks or bamboo (I usually use bamboo but just regular sticks are fine too)
~ Popsicle stick (to spread the tanglefoot)
Sticky traps are very easy to make, I just hate doing it because I do not like the sticky tanglefoot. It is kind of like sap but it does not dry up, luckily it will wash off your hands with soap and water. It is surprising that it does not dry up. I have had this same container of tanglefoot for at least 6 years now, with a crack in it so it does not seal up well, and yet it has not dried up.
Now, on to how to make the trap. I suggest to use the florescent yellow paper, I have tried orange before
but it did not seem to work as well as the yellow. I buy 8 1/2 x 11 paper and tear it in half. All you have to do is take your piece of florescent yellow paper and put it on the stick or bamboo.
Then with the popsicle stick spread the tanglefoot on to both sides of the paper. I try to spread it as thin as I can so the color shows through.
