Bugs phase through base walls

[HohenhiemPrime]

No matter how i seem to build it bugs can get into my base by just walking at the wall a bit and then they phase through. This wasnt really a big deal when it was just some worker ants. But apparently the longer you play this game the more larva attack your base and more frequently. I am at the point at almost 40 days in game that i cant even leave my base anymore. Because they all phase in through my traps and walls and wreak absolute havoc on everything inside.
