Great! From each 12 gallons of compressed (smashed) fresh flower heads you should be able to still (wood-alcohol setup) about 6 fluid ounces of essential oils. These oils will contain about 0.1% pyrethrins. The mixing rate for application is 1 to 2 fluid ounces per pint of water.
Alternately, you can obtain a 40 oz bottle of "Bayer Powerforce Multi-Insect Killer" from a nursery for about US $15. It contains 0.75% solution of the pyrethrin "Cyfluthrin" and the rest is inert ingredients. The mixing rate for it is 1 to 2 fluid ounces per gallon of water.
