I can’t speak to Nexgard but I can speak to your yard. I am in Texas & due to the tons of rain we got in May, all fleas, ticks, Mosquitos, midge flies, etc have been just awful so far this summer. Like you, I hate using chemicals- I have 6 dogs, 6 aquariums, a pond & 4 kids… So I try to use as much homeopathic stuff as I can. I have also tried the DE inside & outside of my house. I tried salt which didn’t work for me either. The fleas & ticks have been something else- I pulled two dozen ticks off one of my german shepherds & had never seen ticks on any of my dogs before this. I did a lot of research as I had another issue on top of fleas & ticks- my neighbor has a chicken coop in his backyard which was causing a massive explosion of flies that effected my yard & home. Ok so long story short, I finally broke down & bought something called Cyzmic CS for my yard. You add 1/2 oz of this to a gallon of water in a pressure sprayer. I couldn’t even smell it when I sprayed. The following day 75% of the flies are gone. It’s now been a week- I haven’t seen one tick, flea or fly for that matter. You might want to consider this for your yard to help. You can use indoors also- it won’t harm plants or animals but will harm aquatic animals.
By the way, one of my dogs is on Revolution & the rest are on Adams flea collars & Pet Armor Plus. Good Luck!
