When you sew native pollinator seeds, stop mowing, and allow natural meadow to emerge an replace a lawn, you will always have some neighbors who will complain.
Usually they escalate their complaints by claiming that rats are mosquitos will be drawn to the dense vegetation.
The irony is that these same neighbors usually have birdfeeders, and a simple game camera or spotlight can quickly confirm that these feeders are what draws rats and other rodents at night.
I’ve noticed that since my yard cum meadow now has many songbirds and chipmunks and shrews and rabbits, there is usually a hawk or owl watching it hungrily.
Needless to say, I see many types of wildlife at night, but never rats. When I see rats, I see them making bee lines from the storm drains to the birdfeeders in the golf course lawns.
Also, since I installed my mosquito fish ponds, I can go out in my back yard without a shirt for hours. When it was a standard lawn of Saint Augustine grass, it was swarming with mosquitos, mostly invasive Asian tiger mosquitos.
Native ecologies work.
