I responded to your inquiry, kathy, but here's a recapI know there is a difference, but I can't remember why I went with lats. I did what you did and got opinions and researched. I think because I read they can't climb and maybe they are smaller and my t's are all juvies. Softer? Honestly, I don't remember why! I just know it was my decision at the time. We will let the experts weigh in on the pros and cons. LOL.
Pros of BOTH B. dubia / B. lateralis:
-Can't climb, can't fly
-Breed very easily with some additional heat and humidity
-Don't smell nearly as bad as crickets do
-cheap to feed: powder up some dry cat food or dog food. toss in some fruit once a week or two
-once your colonies get going, they WILL NOT stop unless you starve them or put them in a very cold environment. You will likely end up with waaaay more roaches than you need so get lots of bins ready.
Pros of B. dubia:
-grows to a very large size so it is a great freeder for huge adult T's; as well as other large insectivores such as pixie frogs, cane toads, etc.
Cons of B. dubia:
-likes to play dead; remedy is to crush the head before feeding or to tong feed
-burrows/hides; same remedy as above
-harder exoskeleton (but nowhere as hard as madagascar hissers) - nowhere around this.. it's one of their defenses. Most T's will get through their shell just fine but there is still a risk
Pros of B. lateralis:
-runs around a lot and general keeps moving until they are caught - this is great to get a T's attention
-very soft exoskeleton so you don't have to worry about broken fangs
-baby lateralis are smaller than baby b dubia. They appear meatier too - this makes them better for slings/juvis
-don't grow bigger than a large adult cricket - if you don't keep large T's, this is a plus
Cons of B. lateralis:
-fast, fast, fast - if you drop one on the ground, be ready to stomp on it. It will be nasty but it is better than having these guys run around the house. I've never had them 'infest' my home but they live for quite some time even out of their enclosure
-because they are fast, they are not suited for slow or sluggish Ts... I've never found this to be a problem though. Even if they T doesn't catch the lateralis on its first try, it will eventually catch it
Generally, I find both these species great to keep! Feed B. lateralis to sling/juvies and feed B. dubia to adults and other insectivores. Both are easy to breed. B lateralis requires a humid environment to breed successfully. B dubia will breed regardless of how dry it is (in my experience). If you clean out the enclosures once every two weeks, I doubt you will ever have a smell issue. I do monthly cleanings but past that, I start to notice a smell.
I've had escapees but I have never faced any sort of 'infestation.' They will, however, live for quite some time after they escape so you may find them around the house (I have.. and squished them).
