Can I spray miticide once more before the mantids hatch?

The thrips infestation had gotten pretty bad this last week and I'm stressing on it since I have a young plant that is a little behind schedule that will really be affected if I don't do something soon though help it out.

Bought a approx 300 praying mantis egg on 8/3 today is 8/9 and the package said 2 weeks with temp above 70 degrees. Not sure if it matters but it's been in the high 90's to 100's all summer, so maybe the extra heart will help them to hatch sooner?

But yeah I don't want to harm them by spraying but the plants need it. What should I do?

I've been cutting off damaged leaves does that help? Anyways thanks for the advice ahead of time!

Is the ootheca (the mantis egg pouch) situated so you can avoid spraying it?

If you do spray, consider an insecticide that will evaporate and leave no residue the emerging Mantis Nymphs might not like. Removing damaged leaves can be helpful.
