Many people often ask what to use to treat an apartment for fleas. I want to recommend this chalk, it's very effective against fleas and other pests, as written on the label. I've tried it myself and I recommend it. You just need to apply it liberally all over the apartment, on the entire floor, cracks, corners, near baseboards, etc. The fleas will all die within 2 days, along with their eggs. It's sold in markets, in the dikhlophos section, insect repellents, costs 1.5 manat.
