Something I would not have thought about as the venom thaws out is it still as potent? I know this is a bit off subject but in mid december when I was getting wood from the pile out back as I got down towards the bottom I ran into about a dozen brown recluse spiders. They were slow from the cold but moving. Spraying the wood will be on the list to do from now on. Snakes and spiders I can do without!
