I have a plastic lip around the top of the enclosure to allow light to get in and prevent him or insects from escaping.
Also I've done a little looking around on this subject. I found this in an older thread:
"As a chemist, I have checked on the web to see the chemical composition, and there is some research:
"A 2006 study done at Clemson University used Gas Chromatography and Mass Spectrometry to determine at least two of the compounds present in the stink bug odor: the aldehydes trans-2-decenal and trans-2-octenal. These two compounds are used in the food industry to add flavor and aroma to products. The trans-2-decenal, also known as decenaldehyde is described as having a “powerful waxy orange aroma” by the Joint FAO/WHO Expert Committee on Food Additives (JECFA).
trans-2-decenal (decenaldehyde)
trans-2-octenal
The trans-2-octenal is described as having a nutty flavor and an odor described as waxy or like a cucumber. In the world of food chemistry it is can found used in bakery items or dairy products."
Since these do not seem poisonous, we put another in his cage and he hunted it preferentially to the crickets and meal worms. He has certainly developed a taste for stink bugs, and it doesn't stink when he eats them and so far no problem."
I've read responses from several people that say they feed these off and have seen no negative side effects. He seemed fine today after the one he ate yesterday so I threw another one in there when I got off work. His response was instant. I've never seen him react that way to a feeder. He literally charged across the cage for it. I like to play it on the safe side when it comes to my Cham so I don't think I'll be introducing these as a regular feeder, even though he really seems to enjoy them
