Oh ok so my other 13 Ts will get the same symptoms? Can you get the infection treated ? Also what shall I feed my Ts then.? I feed my slings bean weevils are they ok ?
I can't answer the infection question, but I would like to suggest red-runner roaches as an alternative feeder. I 'think' I remember you getting some Ts from the spider shop. The spider shop seem to usually have red runners in stock. They also sell a range of worms for feeders, and sometimes dubia roaches but I have heard they tend to burrow.
Personally I like to mix up my feeders every now and again like it would be in the wild, so I do still use crickets sometimes, sometimes worms (although I have heard they have a high fat content so are more of a treat), then I use red runners as the staple diet. They can be hard to find, I have only ever managed to get them online from the spider shop and once from amazon lol. Therefore I have found it easier to breed my own once I got hold of a decent amount. It took about 9 weeks after them laying eggs for them to hatch for me, heating them at around 24 degrees C, but they are finally breeding! Once they get going they are handy for all sizes of T as the nymphs are tiny so they range through tiny, small, medium, large. They also live a lot longer than crickets, and need cleaning hardly anywhere near as much.
On the cricket and infections topic - that is worrying me a bit now too, but I have heard so much conflicting advice about it. Some prefer feeding crickets for various reasons, and I did hope that if I got mine from reputable sources like TSS, then they would be cared for properly and not carry infections....?
