  • #7. Houston

Although the state of Texas has plenty of dirty cities, Houston ranks top of them all for having the third most pests in the e tire state.

  • #9. San Francisco

The major plague facing San Francisco is human waste. This inability to deal with human waste effectively has landed San Francisco on this list in 9th place. In San Francisco, there are beautiful, picturesque areas but then there is the rest of the city, which has a moderately high population of homeless people. As it is, people living on the street do not necessarily have access to public bathroom facilities which is why they are often forced to relieve themselves out in the open, and this does not help the filth factor. A few years back, the sheer amount of human waste on the escalator of the BART station forced the station to shut down until a HAZMAT team could take care of the problem. This sort of scenario is sadly not uncommon in San Francisco.

  • #10. Miami
