If you have a lot of bug issues around the house, dogs (NO CATS), garden... Stuff is magic. I get a 16oz bottle every year and use it on all of the above. It does have a bit of odor to it but fades in a day or two. Get a garden sprayer and mix up a gallon at a time. Same stuff they use for termite treatment except in a much higher dose for initial treatment. I spray it on my camping clothes and my tent. Mosquitoes land and will very quickly start to twitch. On clothing it will last about 5 washings and still be effective. Very low toxicity to humans and dogs (I spray them too when they get into a bunch of ticks, can also make a flea dip) however very toxic to cats for some reason. Our local feed & seed sells an 8oz bottle for about $10 and will make several gallons.
