Is this for sure true. Ive heard not and it was only a kill on contact, But stays around for a while. Doubting eagle 20 is systemic same with floro mite.
Eagle 20 says right on the label it works using systemic action and also is not intend for use on food. It is for turf grass.
Imidicloprid is probably the most systemic as it can stay around in trees for years and most vegetables for several months.
Floromite is not a true systemic however it uses what the manufacturer calls "residual control" this is a red flag in my book. It is only approved for use on greenhouse tomatoes. You can wash residue from tomatoes, cannabis resin is sticky.
Avid also uses this "residual control" mode of action . also intended for use on "ornamental s" .
Home defense. Well the first ingredient is classified by the epa as class C carcinogen, and the second active ingredient causes endocrine disruption and the shit stick around for well over a year.
Also most of the above are intended to be sprayed except imidi. Spraying these chamicals is not a good idea indoors, most if not all the labels warnings include long sleeves, head gear, respirator and other gear. I have not seen any one of these products label say they can be used indoors, artificial lighting will not break things down quite like real sunlight.
