Make sure you have got a spade with you and then make sure you got it in a hot key. Dig when your back is against the wall and you will somewhat be stuck in the wall. If not, your back is not close enough. Do it once more with your back still against the side you want to go through and you should be able to get through. With this you can enter many places that you are not up to, like get to Twin Blades tent before doing Wasp Queen.
