my dog had fleas and this stuff killed them all! it has IGR (insect growth repeller) which kills the offspring of fleas. It also killed some roaches that i wasn't aware were crawling around my building. NO smell afterwards and it doesn't leave behind any liquid/spray... just make sure you place newspaper under each can b/c the spray will leave behind some moisture.....but no messy clean up.... Works just as good a Precor and is half the price.
