Thought I might pass this cost saver along..... A cpl weeks ago I had a severe infestation of the dreaded "SPIDER MITES" in my indoor flower room. I first tried an alcohol/water mix but with limited sucess. Then I went to my hydro store and my man there suggested FoxFarms spray called "Don't Bug Me". He said its a natural spray with no petro chemicals as the active ingrediant and the shit will break down after a cpl of days and become inert and harmless. I bought a 24oz bottle for 16 bucks and tried it. The shit worked great but didn't last long cuz I had 80 plus plants to spray. Well as it would happen, the day before I washed my 2 taco bell dogs and dipped them in some flea and tick dip. Since the instruction said I could let it dry on them I read the ingrediants and wouldn't you know it, it had the same active ingrediant as the Don't Bug Me (pyrethrum) but in a slightly higher concentration. I did the math and mixed up a solution comparable to the don't bug me and literaly drenched my plants on the tops and bottoms with my homemade spray. That was two weks ago and as of today, NO SPIDER MITES and the girls are doing well with no loss of any plants. Here are some picks of the girls I took yesterday. They look thin because I trimmed as close as possible to the flowers as I could to get as many mites and eggs off before I sprayed. I was gonna trim them anyway cuz I lolly pop my plants...take a look... Oh a side note, since the dip is concentrated the cost per gallon of homemade spray is about $1.00 per gallon. Good for outdoor growers who might need a lot of spray .
