i was told it was illegal to hunt squirrel in WA state. what are the seasons and what type ca be hunted?

Well yes... It is illegal to hunt squirrels in washington.
The reason there are no squirrel hunting seasons in washington is because of how many different native species we have. Most of them are on the protected species list.
So, even though it's ok to kill Eastern Grey squirrels (which are non-native invasive species) they can be hard to differntiate between Western Grey squirrels, which are protected.
Plus, why would you even want to hunt squirrels in washington?
Most of the species around here... like Douglas Squirrels or Red Squirrels, are tiny. You'd have to shoot about 10 just to make a meal out of them.
Well, at least this is the offical reason I was given directly from the WDFW Olympia Office, after I asked the same question to them.
okay well that helps haha thanks
