Lice in my seed box

There are a lot of book lice in wih my seeds I put them into an air tight tub months ago and there still alive.

Will the seeds now all be duds/part nibbled?

I can kill the beetles with indorex spray but will this sterilise the seeds?

I thought that might sterilise some of the seeds as well. I guess I have nothing to loose in trying as I'm sure they'll eat the seeds eventually

Thanks I'll eat all the ice cream this week to make room for the seeds and kill the * off.
