Green Laced Wing eggs

I've been hanging some of these little cards or tabs that have these eggs of the Green Lace Winged beneficials stuck to them, but the trouble I noticed is various winged insects, i.e yellow jackets appear to be eating the eggs right off the cards before they can hatch. Anyone else use these eggs/larvae with success?

No I haven’t but a search revealed a method where the eggs/larvae are placed in a pill bottle with a 1/8 hole in top. May help

Thank you. That could help indeed..at least protecting them until they 'hatched' and allowing them to exit on their own...
