Maggots ¿urban myth or true?

I am planning to introduce maggots in the diet of my animals.I've heard or read about maggots being alive in the bellies of fishes and other animals.But, I have no info at first hand of newts and salamandres having such problem. I know some people that use them as a part of their newts diet, and few of them pierce each maggot before feeding the newts (just to have peace of mind).I would like to know people's experiences of feeding newts with maggots. Has anybody had any trouble with such food for caudates? Is it just an urban mith?
Best greetings

I use maggots for almost all my newt species.

Im one of the careful ones that pierces the maggots when being fed to aquatic newts.
However if I am using squat maggots for juvenile, terrestrial newts, the squats are not pierced, and I have never, in all my years of using them, had any passed undigested.
With the maggots being tough little beggars, you can sometimes see the newts struggling to swallow them though.

There are reports in the literature of maggots being passed undigested. I know a vet tech that when collecting fecals on Bufo marinus in her yard in Florida had late instar undigested maggots passed in the fecals (blowfly maggots).
I would suspect that it depends on
1) species of fly involved (the commonly available maggots are usually the common house fly (Musca))
2) instar

I Did not mention this in my original reply, as the question was about feeding maggots to newts,but, I tried using maggots[not pierced] as a food for Bombina some years back, but stopped this as most were passed undigested.
This is the only experience I have with feeding maggots to toads so cannot say if this would happen a lot.
Had I pierced the maggots though I am sure that this would not have happened.

I heard that commercial maggots i.e from a bait shop, are often selected for their tough skins because the longer it stays on the hook the happier the fishermen. It should be relatively easy to grow your own softer bodied ones.

I tried them with my newts many years ago and did see undigested skins occasionaly,(the insides were gone)so stopped using them.

I have used a lot of maggots (from bait shops) to feed juveniles and adults. I do not pierce them. I have never seen any unexplained deaths after using them, nor any difficulties with swallowing them. I have occasionally seen an undigested skin, but only the empty skin.

I can't say for sure if it's an urban myth. If they somehow do get through the digestive tract of some frogs, that may be why the "stories" got started. As Ed points out though, there are different species of maggots and some may cause problems.

I don't pierce the maggots to make digestion easier, I pierce them so they move at half or quarter speed.
My tylo's aren't the brightest bulbs in the universe where it comes to eating (but certainly come close to winning the pickiest eater contest).

Thanks a lot for all your answers. I was looking for a plain and stright post from an experienced user like Jennifer Macke with feedback from their own experience. Then, I shouldn't worry on feeding my caudates with maggots. On the other hand, does anybody feed the maggots with something to enrich their nutritional value? I buy the maggots from a baitshop too. I wonder how are they cultured (feed).

I haven't tried vitamins yet since I am new to maggot feeding myself (curtsey of my tylo morphs). But I had been thinking of dusting the maggots or adding a vitamin mix to the maggot container.

I feed all my newts and axolotls maggots, which I buy from a bait shop. I am careful only to buy undyed ones, though. The only animals which sometimes pass them undigested or partially digested are the subadult axies.

I know this is an old thread but I thought I’d share my recent maggot experience. I’d given up on them long ago due to undigested remains and lack of interest from the newts, but during my regular earthworm chat with the guy in the local fishing shop (he’s a big worm fan) he suggested I tried some tiny maggots. They stock 3 sizes of maggot, the largest being the blue bottle, then a mid-sized fly (I’d describe it as a house fly) and finally a fly that’s about half the size of the house fly. The maggots of this fly are less than 1cm long and more importantly are softer than regular blue bottles. I think they may be what Morg refers to as “squats” earlier in this thread.

When I got them home I stored them in ready-brek (I can hear Alan Cann cheering – a dry instant oat cereal) in an effort to make them smell like my waxmoths which are greedily accepted by most newts. I received assurances from the shop that no chemicals or dyes were used in their production. So far I have only found one awkward Cynops orientalis that refuses them but that’s no surprise because he turns his nose up at anything that isn’t a bloodworm. Everything else wolfs them down like nothing I’ve seen before and in two weeks of using them regularly I have seen animals that are normally fussy feeders bulk out considerably, become brighter and more aggressive at feeding (normally a sign they enjoy the food). I’m very impressed and will include them as a regular part of my collection’s diet. I’ve not seen signs of undigested skins.

Has anybody considered the possibility of spreading salmonella, if the maggots are grown on pasteurised stuff like bone meal i assume they are pretty safe but when ive seen maggot farms on tv(not recently or often) they were using dead chicken carcasses as food, has anybody contracted salmonella from their fishtank due to feeding maggots?. You can also get small maggots called "pinkies", ive been informed that this is also their natural colour and they havent been died.

    Hi I recently rescued a lotl (i did weeks of research before rescuing) Hes mabey 5 or 6 years of age..the previous owner could not remember the exact age of him. I got him from her as he was or had been picked on by his tank mate another lotl who was bough with him from every younger age, I noticed one of his gills, a middle one at the end had split in two? And is slightly more floppy? He also appears or mabey I'm just over worried to mabey have lost some feathers, is that normal to lose some?...all levels in the tank are fine, but wondered if theres and advice anyone could give me as an experienced owner to a new one.

  • Axolotl Queen:
    @Lanalotl Sounds like the gills may have been nipped by the tank mate. If he is in his own tank and the parameters etc are all good, then he should grow them back and they should go back to full health and strength. However, depending on how old the injury is they may not fully grow back if they have been constantly nipped at.

    Can anyone tell me why this is happening? We just did a water change and after freaking out and whipping around the tank, an hour later they look like this. It won't let me send a pic. The edges of their gills are white and it looks like they have skin shedding off

    That sounds like severe skin damage. If you post a thread on the forum, you can attach pictures.

    It sounds like something went wrong with the water change, so this could be very dangerous. Did you use a dechlorinator? Could it be there are traces of chlorine or soap in the water? (Or for example, in the bucket you used?)

  • Murk:
    Normally, I would recommend taking them out of the tank asap and putting them in a tub with fresh water, but if there's something wrong with your tap water or dechlorinator, that might not help either. Do you have acces to bottled water or rain water?

    I think my axie is dying, he’s never had any issues before, I’ve had him 3 years, today I noticed some fluffy looking stuff coming from his genital area so I took him out of his tank and did a full tank clean to make sure the water wasn’t infected as I thought it was fungus and then I noticed he had a cut on his belly which was only small about 5 hours ago and now it’s spread to all of his belly, what do I do I’m freaking out

    Update about my axie, unfortunately he has died over night, he looked as if he was bruised allover his belly, his mucus layer had also started to come off.

    Hi I have 2 4in juveniles (I’ve had them about 2 weeks and they are doing well I think they’ve grown a little already honestly) but I am supposed to go on a 5-6 day vacation in October about 3-4 months from now. I am wondering how I should go about their care when I am gone. I thought about putting them in separate (fairly big) containers with live plants and/or bubblers with a fan in the dark and either fridging them (my last plan) but I am hoping to to either have someone I trust come feed them and turkey baste waste out or just leave them out and clean the containers before we leave and have someone come check on them once or twice. Does any of this sound like a good or bad idea? I want the best for them. All help appreciated :)

    Could be he's just excited, spooked or temporarily stressed, which could pass in a few hours. It could also be an indicator of other problems. Do you have any recent water parameters?

    Help! I got my first axolotl two days ago and they have stopped eating. They ate a few frozen blood worms the first day and haven’t eaten or been interested in food since. I feed them frozen blood worms and the tank is around 64 degrees. I do have a filter that moves sometimes and I noticed them swimming up to it, I have a new filter and a fan coming today or tomorrow. I leave the worms in the tank or a little bit before taking them out so I don’t know if they ate when I wasn’t looking. I know it takes a while for them to digest. Does anyone have any tips or knowledge they can share? The pet store I bought them from didn’t have gravel or sand in the tank so I’m not sure if theres an issue or if I’m just impatient. Thank you!

    @MuggleMiChu I would say try live black/blood worms untell they are full or just turn there head away ( that's what mine do) if that does not work try to get some live brine shrimp and see if they eat that. baby axolotl prefer live food over frozen food as the frozen food is too cold for them or they can't eat it in one go( that's if you do the blocks) mine eat chopped up frozen thawed shrimp. as for them not eating from what I have experienced with my second axolotl, I got her when she was about an inch long and she ate every day, when they start getting 3-4 inches long they will gradually slow down there eating. and if you really want to do substrate I would do sand because if they do ingest a little bit it won't hurt them.

    Thank you so much for the information and advice! They are eating again, they ate a lot today. I think it might have been stress from the move or digesting old food, I also noticed they ate some of the food left in the tank (I removed the rest). I’m going to keep the tank bare bottom.
