Rough earth I believe. If so they are normally an ok snake to have around. I normally just pick them up they are pretty docile don't ever really get aggressive at all. I tend to let all snakes lie. Do a lot of catch and relocation of snakes even rattlers. But I guess if your unsure better safe than sorry. No sense risking getting bit by something that could be poisonous.
I was told snakes are venomous not poisonous
