I need advice on hatching green bottle fly pupae!

I'm a complete beginner. My first spider just arrived a week ago.

The pupae were originally on the heater in a moist container with holes on it. I found out
(the hard way) they die on the heater in too high temperatures.
I got rid of the dead pupae and put some new ones from the fridge on a moist paper towel in a well ventilated container on the coffee table. The room temperature there is 25-26°C. One of the flies was darker than the others, so more mature I guess, but none out of the 5 pupae has hatched so far and it's been about 3 days.

My spood just moulted, she hasn't eaten for a week and I will need to feed her something soon when she decides she's ready. (Got some mealworms as well, but they are much bigger than her, that's all I could get. I heard they bite, so I would prefer the flies still, have those as a backup option.)

Can anyone please advise on what I'm doing wrong or if I'm just impatient? All help much appreciated! 🙏🏻

You should store them in the fridge, then take enough out to feed and put them in a deli cup and wait for them to hatch, maybe 3-7days, and then then feed them to your spider.

This takes up to 10 days.
Of you got some maggots, this will be fine for now.

That's what I tried with no success so far. My jumping spider accepted a mealworm today, she must have been hungry after moulting. So proud of her! Will keep on trying to hatch the flies.

Cut up a mealworm and leave part of it in the enclosure. They'll scavenge on dead prey

I gave one live one (with the head smashed to slow it down), it moved just enough for her to notice and she jumped on it like a true champ! 😍 It's been a couple of hours and she's still eating it. :)

Just mentioning from experience working at stables, dairy and fish farms. 45 F to 75 F is ideal for maggot growth. Colder temperatures interrupt their life cycles. They are hypersensitive to light, especially UV. Preferred habitat, manure or slaughter offal. These habitats are so problematic many locations in the US have 24 hour abatement ordinances.
Maggots not maturing. Numerous chemicals are on the market that inhibit or prevent adult flies from being able to lay viable eggs, chemical sterilization such as Equitrol, or prevent maggots from maturing.
, various chemicals that can be sprayed over wide areas such as pastures. Interrupting the life cycle is big money for folks like Monsanto.
If you consistently are unable to raise or mature the maggots into flies, suspect those chemicals got in on things. State to state transportation or shipping often requires chemical treatment.

Equitrol and similar acts as birth control or leaves the larvae unable to mature. It is added to the feed of ruminants so their feces turns into fly abatement zones. Has no effect on mammals.
