Nice to hear from you again. Pet stores specializing in aquarium fishes often carry them, or can order for you. A few inter-net dealers will ship also, depending upon tempersature and locale.

Midges will lay eggs in bins of water if they are present in the area (1 species or another is found most everywhere). Mosquitoes and all sorts of other insects will also arrive…the larvae of many are great foods for amphibians, but of course mosquitoes can be troublesome or even dangerous. If you add dried grass/hay, daphnia will usually appear as well.

I have a small outdoor pond; in the warmer months I seine it with a fine net and toss most of what I catch into my newt and fish tanks…no maintenance at all, and very interesting.

Good luck and please keep me posted.

Best regards, Frank Indiviglio.

I use frozen ones quite a bit for my amphibians, but I like to feed live whenever possible….
