Josh's Frogs 32 oz Fruit Fly Cup and Fabric Lid- 20 Pack

I'm a repeat purchaser of these fruit fly culture cups. I'm also cheap, and I wash and reuse these cups and lids until the cups finally crack and the lid's fabric lining becomes too thin to contain flies. Despite constant use, I still have most of my first order of ten cups and lids from 2022. I've also used them for housing the occasional jumping spider that I find indoors in the winter months, when it's too cold to toss 'em back outside.

Been using Josh's Frogs fruit fly cups for years and they are super great to make cultures out of! Very spacious cups for more production, but also easy to get flies out of when you need them in comparison to the very short fruit fly cultures I've seen at stores sometimes. Fabric lid is great for ventilation without flies escaping. My only gripe is I wish they weren't so expensive for plastic cups.

Got a regal jumping spider female. Seller said she was bred and not wild caught. They lied. I now had a bimonthly subscription to the Bucket O Spiders club. I needed to make both fruit fly cultures AND contain slings (baby spiders / spiderlings) in containers that were breathable but with NO GAPS to slip through. For spiderlings, flip upside-down and elevate on a wire rack (so that the air filter on bottom can breathe. You can poke tiny pinholes for extra air using a very thin gauge needle. This should hold your slings for a few weeks (people advise separating them before this but I luckily didn’t have much of an issue). For flies, leave right-side up and use as intended. You can reuse these if you have the stomach to wash them after the fruit fly medium inside… marinates and degrades. The containers themselves are sturdy enough for reuse. Filters can be lightly scrubbed to clean most residue off (contaminants would still be present, so not a good practice if you’re a research lab). Worked great for the 8 Buckets O Spiders I had to raise and their endless supply of food I had to raise (both drosophila melanogaster and drosophila hydei. Never did bottle flies though). Honestly? If you like bugs, these are great to just have on hand. Much better than the Jar of Doom (jar with holes in lid).

Lids Don't fit cups, this time recieved tiny whole lids. They don't fit cups. Cups crush easy fighting to put on lids. The left override which are the bigger wholes don't fit either so might be a different deli cups than before. Afraid to order more. I'm going to try and stretch them out, this my 7th order 1st time the cup size seems off.

I prefer this kind of cup, with the fabric vented lid because it ensures that fruit flies don't escape. I've used the ones before that had a plastic lid with small holes throughout to vent, and the flies will climb into those holes and get stuck or actually make it out of the container. This product is exactly what I need for the purpose I use them for.

As desired

I have ruined a few of these containers when trying to put the lids on. The lids are annoyingly just a bit off in size, so its a manuver to get them back on. If you put any pressure at all, the containers will crack right down the whole side. If you have a bunch of flies in there, it becomes a mess really quickly. The containers do work, though. I like the lids.

I’m not big on leaving the comments but when I opened my box that I got from these guys, it came with a 50% off DoorDash order and a $100 wine voucher. 10 out of 10 would recommend.

They are exactly what they say they are and haven't broken down on me.

Kids fit a little weird but it works
