I released the 50 ladybirds I bought to help control aphid populations on my acer, but within a few hours they were all gone! I was advised not to wait until nighttime for the release because I was worried they'd suffocate in the box. What might have gone wrong?

Just a heads up, next time you might want to use a greenhouse or something similar if you want to keep them around. Otherwise, ladybirds are made to fly. And if the aphids are really out of control, you can always try a soap and water spray—works wonders!
It sounds like a classic case of ladybirds just flying away! They aren’t going to stick around when you let them go outside. Next time, try releasing them at dusk when they’re less likely to just take off. If you really want to boost your aphid control, consider getting some baby ladybirds—those won’t fly away as easily!
Yeah, babies are the way to go! They stay put and munch more, which is exactly what you need.
Don’t feel too bad! You’ve actually increased the ladybird population in your area, which is a win for future gardens! Just give them some time to settle. They’ll eventually help control your aphid problem if you don't mind waiting a week or two for them to get comfy and lay eggs.
Absolutely! I dealt with a huge aphid issue last year and that method really cleared them up fast.
