Native Bees come in all kinds of shapes and sizes! Some are so small you would never consider them a bee while others like our native Bumble Bees can be quite large.

Anything that is sprayed on plants; pesticides, insecticides, fertilizers, etc... eventually ends up washing off with rain or watering and ends up in the soil and the native bee's home.
As you can imagine many of these substances can be detrimental to the health of ground-nesting bees.
