They're good for ants but not so good for the nest, especially if they are kept moist, they can easily destroy the nest by leaving a wet trail behind them everywhere they go.
I once gave my Myrmica rubra a couple of maggots, but they could easily crawl over the fluon or talcum layer making it possible for ants to escape.
Keep that in account if you give them maggots, personally I prefer meal worms because they can't do much damage.
