I ordered a batch of 1000 and I've had about 50 die total at the very most. This was my first batch of 1,000. Here's what I find works for me (because my first small batch of 200 I lost HALF of them):
- Tank size is critical I noticed the first time around. For 1000 crickets, I have them split up in two ten gallon containers (so ~500 each tank).
- crawling space is absolutely essential. Make sure they have tons of stuff to crawl on or they will smother eachother and kill eachother on accident since they'll all huddle in the same spots.
- drop fresh feeder food every day (I've noticed the fresh feeder smell attracts hungry ones instantly). I also use a syringe with water and drop droplets in the cage in random spots. This keeps them from smothering eachother, and there's still the condensed water gelatins for them to go to if they want it. This I've noticed works very well and they respond well to
drinking water in this fashion.. Just make sure you don't pool the water up or they could somehow manage to drown themselves since they aren't.. the brightest insects in the world.
- make sure your supplier actually gives you good crickets. Sometimes crickets die off because they just aren't healthy or weren't raised so they have good vitals for feeding purposes.
