I have also used Adams, but it is cumbersome if you are spraying a large area - it is a finger-trigger spray. The Precor 2000 is an aerosol, and while that makes it less cumbersome, it seems to 'fly' in the air (think of the old forms of aerosol hair spray). I will likely get the concentrated version of Precor 2000, mix it in water, and use a pump sprayer. I also noticed the Adams smelled stronger and the scent lingered in the area longer.Thank you! I will look into that product. And thanks for the link. I was about to buy this spray from walmart, but i dont know if its as good as the comments are claiming. Its called Adams Flea & Tick Home Spray.
I cannot honestly tell you if one is more effective than the other, as I have been on the flea-fight-battle for many months now. It just seems like I might have reduced the fleas more with Precor than I did with Adams. But, then a lot of other factors come into play as well (more frequent vacuuming and cleaning).
