How can I get rid of these ROACHES!?... They just won't die!?

roaches live on a short life cycle, about 6 weeks, meaning that it can take up to a month for fumigation to start showing results. During this time, you should be vigilant of not leaving any crumbs or leftovers that roaches can eat. also get rid of old books and magazines where roaches can nest. Use a household pesticide, such as ortho home defense, and spray around corners and dark areas. Boric acid is a waste of time, only effective against very small roaches, not roaches. Foggers are a waste of time as well, as they are effective against flying pests, such as gnats. spray every weekend and be patient. Remember that apartment living means that you may keep your home pristine, but your neighbors may have horrible roach infestations, you will never truly be roach free at an apartment, but you can control them.
