Carpet beetles need advice

I have a customer that discovered some carpet beetles.

What solution would you guys clean it with. We have a TNT with a 4ht heater, It's builders grade. So we will crank the heat and steam it but what pre spray do you recommend?

We always add h2o2 27% on lighter carpets. Is 240f and peroxide enough?

I read online that they need to wash every fabric in the house that isn't sealed in a container.

Any help is very much appreciated

Thanks guys
