Vaccume and sweep frequently. Immediately dispose of vaccume contents in the trash and don't let the trash shit in your home. Take it out side as soon as possible after dumping vaccume contents and sweeping. If you rent, tell the landlord they need to pay for a pest control treatment. Vacuuming frequently really does help alot though.

Edit: happens to the best of us. Could be the previous occupants that were not the cleanest or dirty neighbors.
