Not trying to still thread or anything I just had a question myself. Years ago I had parrots. We moved to a new home that had lots of spiders and such so we had to have an exterminator come out. I was concerned about my parrots because they are really sensitive to chemicals, candles, nonstick cookware etc. Things like that are really deadly for birds. We called the exterminator and ask him not to go in the bird room and he assured us the chemicals were not harmful to our birds. Nothing ever happened to any of them. So my question is how can the chemicals they use be different for snakes?
