Best pest control ever!

For the last two years our apartment building did a conventional roach treatment. It never worked: the bugs were back almost right away, and it was a big pain, because everyone had to take all the food and dishes out of kitchen cabinets, put them in airtight plastic bags, and take your pet and leave the apartment for a minimum of 4 hours. So I sent the management an email, explaining to them that it is a lot cheaper and easier to just get a bag of Diatomaceous Earth and give everyone a handfull. Sprinkle Diatomaceous Earth in the drawers, cabinets, behind cabinets, on the floor, on your pet's food! The bugs will die, but people are animals actually get healthier from ingesting the stuff! The apartment management agreed to trying my suggestion, thanks god! Now there is no bugs and no fuss.
For fleas: sprinkle on your pet and rub into the fur; and on the carpet and leave on for a couple of days before vacuuming.
For worms: sprinkle daily on your pet's food or dissolve a tea spoon in water or juice for humans and drink, continue for 3 months.
