Don't like how it says "controls" not kills. Haha
It's systemic in action to the bugs but breaks down very quickly (12-24hrs) .
So yeah it kills whatever is on the plant when it is sprayed but it can't stop re-population between applications.
I need to spray my Strawberry's once every 2 weeks or so and my Aphid problem is bad.
The thing with Aphids is they come from other plants, I have a tree in my garden that is infested with Aphids and those are what migrate to my Strawberry's and Basil each year.
Aphids usually only attack a specific group of plants which that specific Aphid species prefers to feed on (fuck knows where Ganja comes in. lol)
You're supposed to treat your affected plants and remove or treat the source of the Aphids too.
Otherwise they'll just keep coming back each season.
I can't remove the tree and it is too big to treat effectively or cheaply so I have to make do with treating the Strawberry's throughout the season and make do.
