Flies, earwigs, something that looks like mini grasshoppers but they bite, slugs, lawn grubs, black beetles, and white flies. Other parts of the yard many bugs are controlled with coffee, tinys snakes, lizards and slender salamander, but the reptiles and salamanders all avoid the are next to the goose run. The top of the list is the flies, and those mini grasshopper bugs, they get into the house when they get the chance.
I'm cleaning up after the geese a lot and put down shavings in their favorite areas but the fly population this year is nuts.
I heard Muscovies help get rid of flies, is that true? maybe I need a couple of those.
