### ⭐⭐⭐⭐⭐ So far, so good!
*by M***X on May 9, 2025*

I purchased 2 ootheca and separated them into 2 vented containers. Very gently, I hot glued the stems onto slightly larger sticks so they can hang. Everything was packaged well and arrived when expected. The only thing I might suggest is to include instructions on the direction they should be suspended. I may be wrong about this. Ignore me if so. I usually keep 1 or 2 nymphs and release the others in the garden after they grow a bit. Make sure you have fruit flys on hand to feed them. I will check back after they hatch. Edited: well, that didn’t take long. 4 days after receiving them, one of my ootheca hatched out about 200 nymphs. I wasn’t prepared! I had to run to Sedona PetSmart and grab 2 canisters of wingless fruit flies to feed them. I sprayed and fed them the next morning. They ate all of them (big shake of the fruit flies). I had separated the ootheca into 16oz.deli cups with vented lids. Everything was good until the morning of the 3rd day when about 3/4 of my nymphs were dead at the bottom of the container. Same thing with egg number 2 which hatched 3 days after the first batch. Guess I need to read up on them again! Peace!✌️
