What can we do more or less our pest problem surrounded by our vault?

My Fiancee and I are living in the basement of her parents' home. But we hold a problem with bugs. There have be roaches, spiders, crickets, ticks, ants, dirt dobbers, wasps, and other insects and pests down in our basement. We are lately now transitioning to live down in the vault, and we are making it inhabitable. It still requires cleaning on the floor especially.

Outside, we have pet chickens, dogs, and cats. This is a big concern, because we don't want to put any pesticides or poisons out there that may hurt our pets.

What can we do nearly this insect problem? Is there a safe or natural solution? Where can we find it?

Thanks for your help!

Answers:    This bug cleaning should have be done before you moved in. I deduce about harmful pesticides, but one home we bought years ago be overrun by large cockroaches! I am terrified by these fantastic bugs. We kept our furniture packed in a building on the property. Bomb sprays did not even dent the problem. A bug man come out and sprayed, and they still returned later. Finally I bought Boric Acid, it is a powder. I put this powder all around the kitchen, surrounded by corners, in cabinets and around cabinet. Left it for three weeks, came back and cleaned up. No more bugs. Lived nearby for four years.
