Some of my hard work has paid off

6. wow

we get grubs in the lawn and in outdoor potted plants (and of course in the corrals). they will come to the surface if the ground is saturated, but I have never heard of them migrating en masse indoors.

I wouldn't spray them indoors, just sweep them up and throw in the trash. if they are damaging things (they tend to feed on roots, but some eat other things) you can spray outdoors. a barrier of diatomaceous earth or even pyrethrin powder (or spray) will probably stop them at the doorway but needs replacing after rain.

from a couple of posts it does seem like you are struggling to keep a yard, perhaps thinking of a nice apartment or condo with included landscaping might be something to think about.
