In certain parts of the world an entire lifestyle has been built on the logistics of the old pesticide methods. Good luck getting rid of them. Furthermore, and this matters enormously, Walbachia is still a nuisance. If Walbachia replacement is deployed, a resident can quite reasonably say: “Great, dengue risk is lower, but why am I still getting eaten alive in my backyard?”. That resident may continue demanding spraying, larvicides, traps, pest control, etc.
