I feel your pain sometimes things are beyond our control.
I tried to help the native bees in my neighborhood a few years ago and all it resulted in was people getting stung/ me spending/wasting hundreds of dollars on plants/ bees dying from staffs efforts to control them/ getting obessed about sprays ect/ which leads to me getting more meds for my autism and having group home staff have orkin come.
this spring i'll kill the remaining plants and give up. no sense in luring them to all die by a pest control company.
i highly do not reccommend this for group homes. end of rant
