Answer: The netting damage on your eggplants (also on peppers and tomato plants), sounds like feeding by Japanese Beetles. Many insecticides are labeled for Japanese beetle control on landscape plants. Examples include acephate (Orthene Turf, Tree & Ornamental Insecticide), carbaryl (Sevin and many other brand names), cyfluthrin (Bayer Advanced Garden Multi-Insect Killer Concentrate), lambda-cyhalothrin (Spectracide? Triazicide? Soil & Turf Insect Killer Concentrate), esfenvalerate (Ortho Bug-B-Gon Garden & Landscape Insect Killer Concentrate), and permethrin (Spectracide? Bug Stop Multi-Purpose Insect Control Concentrate and many other brands). Neem extracts (Bon-Neem) deter Japanese beetle feeding but may not be adequate against high populations.
Mushrooms growing in the potting soil of houseplants are usually there because the potting soil is decomposing. It's a natural thing; you can pull the mushrooms out and try to make sure the potting soil isn't too moist all the time. Or, you can repot your plants with fresh potting soil.
Best wishes with your garden!
