This is a spray for surfaces and upholstery that is supposed to kill fleas and their eggs and stop their growth. It really doesn’t seem to do very much.
We have had a terrible flea problem this year. I tried several solutions before I bought Frontline for my poor, harassed dog, Maggie. The Hartz Spray made Maggie (and my son’s dog) go crazy trying to get it off their skin. The flea collar helped a little but wasn’t up to the task. This spray was another thing that I tried, but it was hard to say how ineffective it is before I got the worst of the problem under control.
But now that the fleas on the dog are doomed, and have pretty much stayed away from her, I’ve washed all the bedding, couch covers, etc., vacuumed and continued to spray areas that seem to still be breeding fleas. This Sergeant’s Gold spray claims to kill adult fleas and eggs and ticks, and be effective for 210 days. It’s not effective for even 24 hours!
I bought this spray because it had different ingredients from the Hartz Spray and I figured I’d give it a try. It contains an active ingredient called Nylar. This is just their name for the actual chemical ingredients which are a combination of products that both kill adult fleas and prevent small fleas from making the changes needed to become adults. It is also supposed to kill flea larvae.
The actual chemicals are 2-[1-Methyl-2 (4-phenoxyphenoxy) ethoxy} pyridine, and Tetramethrine [(Cyclohexene-1, 2-dicarboximido) methyl 2, 2-dimethyl-3 (2-methylpropenyl) cyclopropanecarboxylate, and 3-phenoxybenzyl- (1RS, 3RS; 1RS, 3SR)-2, 2-dimethyl-3-(2-methylprop-1-enyl) cyclopropanecarboxylate.
Well, the area under my desk, and near my bookcase must be a breeding hot spot in our house. Every morning when I walk into my office a flurry of tiny fleas leap onto my socks and legs. Fleas like white, and the white socks just attract them! This is not all bad, because they also have trouble jumping off the socks, and I can easily catch and squash them. But it also reminds me that the flea problem is still with us. So I have been spraying at least once, sometimes twice a day in these problem areas for a week now, and there are still new tiny fleas every day. This does not seem like the 210-day control that is promised! Not even 24 hours is more like it.
Nevertheless, I now have this can, and I will use it up. It is safe to use on fabrics. You are supposed to just lay down a mist. It’s not for use on the pet or on your own skin. The smell isn’t too bad. Maggie doesn’t get up and run away when I spray surfaces near her like she does with the Hartz Spray.
Another drawback is that it is an aerosol can and I would prefer a pump spray as more environmentally friendly. But, as I said, I wanted to try a different active ingredient.
If you haven’t purchased this, I would say “don’t bother!”
Update On Jul 14, 2010: I have learned that these types of sprays that interfere with the flea life cycle can take up to 6 weeks to be effective. So, as part of an overall flea control program, this might be helpful.
