RE: spraying for bugs, etc. when and what


Bifenthrin and Fipronil aren't systemic & also don't control grubs if they
are a concern.

Imidacloprid is considered "practically non-toxic" to earthworms. Where this
myth came from I'll never know.

Imidacloprid wipes out earthworms.

Bifenthrin and Fipronil are almost harmless to earthworms.
