I've been using Bravecto and Nexgard for the past 4 years and it really should be emphasized how much of a seismic shift these meds have been.
I've had dogs all my life and live in a very tick-prone area. Nothing ever really worked, to be honest. It was a constant battle of attrition. I had to spray the house with nasty chemicals every few months cause that was pretty much the only thing that kind of tipped the balance against the ticks. I frankly don't know how we didn't get Lyme disease, we were exposed for decades.
Since these new meds appeared, ticks have completely disappeared from our property. They only provide 1-3 months of protection, but they're so effective at eradicating the parasite population that I've only had to use 3 pills in the past 4 years.
There might be external effects happening at the same time here.
I grew up on a island with a lot of ticks. Being a kid and spending time on fields and in forests, we constantly had to remove ticks before heading home.
But now 2 decades later, visiting the island again as an adult and expecting having to do the same after walking around the forest, we didn't find a single tick on ourselves, when it would easily have been a couple of ticks each in the before-days.
So many parameters being different though, so hard to reach any conclusion, maybe my blood is less attractive, maybe we weren't physically intensive enough, maybe the wrong season, but maybe there are other chemicals at play too that wasn't there before.
