Ants and planting
I have a large ant nest under a dead lilac bush. How soon after I have sprayed the ants can I plant the new lilac bush? If the ants aren't all dead, will they just kill the new lilac again? I live in a zone 2 climate in Canada.
This can depend on the type of ant and how bad the infestation is.
I certainly would not plant until you are sure the issue is resolved.
