There are many spiders in the firewood that's stored outside, which hitch a ride indoors when the firewood is brought inside. Looking for a product to kill these pests outdoors, that would be safe on wood to be used indoors. I've treated the areas surrounding the firewood stacks to kill spider food, but wolf spiders are mobile and love woodpiles.
We do not recommend treating firewood. We would suggest that you treat the surrounding areas and remove their harboring areas and food source. Especially if the wood will be used in the future for burning.
