I have used it on indoor plants; especially effective for root
mealybugs. However, Bayer markets a variety of formulations
for use in Europe, and when last I looked, the French beekepers
association was up in arms about it, as they believed that it
was translocated through the plant and got into flower nectar.
Their bees picked it up, took it home, and it put paid to the
hive. I don't use it outdoors.

I neglected to record that Bayer vigorously disputes the assertion
that imidacloprid gets into flower nectar. Caveat emptor.
