I am not sure your question is well founded, sorry. Very few gardeners use chemicals to the complete eradication of all wlidlife. What would be the point of that? No insects, no birds, no whatever.
Gardens are one of the country's most important wildlife refuges, chemicals and all. I use some chemicals when I think it wise, after all I spend a great deal of time and money on my garden. It belongs to me and is my main hobby. Wildlife teems.
I live in the New Forest, and my garden has more birds per sq.m. than the NF.
