Permethrin mixing with 20 Gal Gilmore Sprayer

I have had to change sprayers frequently and now have a Gilmore 20 gal. Didnt use it last year because we had a million dragon flies, thus no mosquitoes. I spray to eliminate mosquitoes and ticks. Every new sprayer I go through "what is the correct amount of Permethrin to mix with water to fill the 20 gal sprayer to be effective?" The instructions on the bottle are conflicting. Some in oz per 1000 sq ft. others in oz per gallon. I just need oz to put in 20 gal Gilmore sprayer and mix with water to fill sprayer bottle. I have been using Permethrin for probably 8 years and it is especially effective against ticks - we have Goldens.


Please specify which Permethrin based insecticide you are using as every permethrin product is different and may require different mixing rates. Thank you and I hope to hear from you soon!
