How can I get rid of bugs on my firewood before bringing it indoors?

Before bringing in firewood full of hidden bug eggs & termites, it should be sprayed many weeks before then. Years ago, Diazanon was the pesticide to use, outside and let it air-out 6-8 weeks before burning the firewood. Diazinon is long/gone. So what do you spray on your firewood to keep the bugs from hatching in your house? Ive literally thrown the firewood on the patio to dislodge the crawling critters on the outside, but that’s not enough. Yes, I have wood boxes under the eaves, close to the house & that may be all I can do- is leave it outside and let the cold air in to get more firewood.
