Consider replacing your lawn with something better for the environment. Or take easy steps to help native pollinators that don't include replacing your whole lawn. Some options include:
-Native grasses if you still want a grass lawn, possibly with native wildflowers included if you want to help native pollinators and/or are letting it grow long. Native grasses have deeper roots, require less watering, and help prevent soil erosion.
-Native groundcover plants. A popular one here in my area is clover, which is great for bees, and it stays short, so no mowing!
-You can also consider keeping your normal lawn but leaving a small patch for pollinators by not moving that patch most of the year. Let things like clover and dandelion (or whatever is native near you) pop up there naturally, or scatter some native wildflower seeds in the area
-Another thing you can do for pollinators and native insects is leave your leaf litter in part of your yard. Around the base of a tree is a common choice. You don't have to leave it in the whole yard, but insects hibernate in there in the winter, and many, including fireflies, lay there eggs there and have their larval stage there.
