My home was starting to have a roach problem. Icalled around to the local pest control companies and to find out after a year they could still could not Guarantee that I would have no more roaches at a $100 a month. I called GNL distributing to see who they would recommend seeing that they were a supply company. Come to find out they have a wide variety of pest control supplies that I could purchase they are pet friendly and I could do it myself. The owner explained how to use the products very well it was both safe and very easy and to my astonishment after only one use I have roaches no more, I did a second application a week later though. I also purchased a flea spray for the sand fleas that were terrorising my family after only 1 use of this also I had no more please. The only downfall is that it came in a very large container which ran around a $100 at that time which was very affordable compared to the other companies I would highly highly recommend G n L distributing to anybody who has had the same similar problems as I And who don't want to wait a year to get rid of roaches. Listen and follow the directions just as he explains them.
