Most efficient way to buy Ultracide's 3 ingredients, but in concentrates to mix in a sprayer instead of aerosol...

I sprayed the precor igr we got from you last week, but haven't used anything to actually kill the fleas yet aside from repeatedly sprinkling & vacuuming up boric acid & diatomaceous earth powders. I want to get something better now, and I understand Ultracide's pyriproxyfen, pyrethrin, and permethrin is a successful combination for indoor fleas- I just want to get them in the most efficient & economical way possible, and am having trouble pinning down which if any products will have these in concentrate form without overlapping if possible. Or best to just stick with the aerosol cans of Ultracide? Any advice would be appreciated.


Pyriproxyfen is the IGR in Ultracide so the equivalent to that would be something like Precor IGR. Pyrethrins would be something similar to ExciteR Insecticide, which helps the product work quicker. Permethrin SFR would be similar to the permethrin in Ultracide. All of these products can be used indoors, but the concentration would be a lot higher than in an aerosol. Either Ultracide or the other products mixed together will work very well for fleas. We would just make sure that you are vacuuming daily for 14 days and then doing a second treatment. If subsequent treatments are necessary, you will repeat the initial process.
