Bug the bug MD works very well I sprayed some outside my door because I saw a roach coming under the door I haven't been home this much this week but when I left I sprayed the apartment when I came back I found about five dead Roaches on the floor so far I've been in all day and I caught three running around and I just sprayed them with the bug MD I feel much better that I don't have all these roaches running around the house I mixed say one to three one bottle and put three bottles of water into the big spray bottle. I used two bottles so far in the picture you can see what this bottles look like and plus the spray bottle thank you very much bug doctor sincerely missed the Richburg
