Cricks will do really well with a heat tape but not if you heap in a bunch of vegetable matter at once because the moisture levels will kill them. With the overhead heat, it will probably mitigate the excess humidity. What I do is use small cups with paper towel and water or for bigger ones I...
I'd go broke buying cricket feeds. I get 50# bags of non-medicated chick layer mash at TSC. I think it's about 15$ for that size bag and it will feed thousands of crickets plus give you something to grow mealworms and superworms in.
My experience is that crickets are just more popular with lizards in general because they move more. I don't try to force dubia too hard, the species that will take them I feed them too, otherwise I feed more active prey items.
I am not aware of anything that leads me to believe the claims as of right now. So far as I know, from the peer reviewed literature I am aware of, that 24-48 hours prior to feeding is the critical gutload time for commonly used feeder insects.
I would think the odds of a lizard getting parasites that are persistent would be unbelievably low. Most of insects would probably be the intermediate host and so as soon as you quit feeding that species the chain would be broken. It's not a bad idea to do an occasional stool sample anyway. I'd...
Crickets are one of the best studied of the commonly available feeder insects and much have been proven about how to gutload them in literature not just some guy on the Internets opinion. I've been feeding crickets and mealworms to my herps since for a very long time. Part of the anti-cricket...
Crickets keep pretty good when the humidity is not too high ime. The smaller ones can handle higher humidity than adults. What happens is people fill the cricket box with a pound of greens and humidity shoots through the roof and once a few die in a higher humidity environment the rest follow...
For the roaches, lots of places to order, but I had good luck with KFC feeders. Crickets are not hard to keep alive but they may have been in bad shape when you got them. Too much moisture will cause a mass die off. I use cotton balls in a disposable lid and change the balls out daily and...
I would stay away from water crystals, they have been implicated in numerous lizard deaths. No telling how many where they were the undiscovered cause.
I've never found a suitable replacement for crickets. I keep a lot of different species of insect eaters and most of them do very well on crickets. I find them pretty easy to breed and I usually have a box or two of them going, I also order some from Flukers, too. I've kept the Dubias for a year...
I have a different set of tools for each species I keep. Internal parasites can spread anytime fecal matter is transferred from one cage to another. If a tool or feeder comes in contact with fecal matter, then is moved to another cage there is some risk. As for sick feeders, like all food items...
I just order the chow and eggs, it works out pretty well that way. When I lived in the midwest, Mulberry trees were very common. You could collect the leaves in some parts of the country pretty easily.
Most commercial gutloads have not been tested. Specific to crickets, none of them tested except for Trex brand produced a suitable CA:P ratio after 48 hours of feeding. You need about 8% Calcium and the product labels of one gutload were consistently shown to not meet the minimum specified on...
