Hey guys. I was wondering if I can put my toadlets in a large rubbermaid outside so they can eat wild insects. I was thinking I could attract small wild insects to the container. Like maybe aphids or wild fruitflies or even springtails. I got some d.hydei but I read they're hard to breed. Plus I only have 3flies left. D: Any ideas?

I'm hoping to release a great deal of them soon but just wanting to keep a large number like maybe 20 to get them to grow a bit bigger. Just in case if I ended up keeping 5 and said like almost all of them died cause of whatever reason I'd still have some left over. Since toadlets are quite unpredictable
