Hello,

If you visit the website
http://www.nobugs.com/Home_Sub/Home_Sub_NoTermites/PremiseBen/Product.htm
(bayer USA), you will be informed about the effects of the Premise that a
chemical used to kill Termites. The active ingredient of this product is
imidacloprid, the same used in Gaucho. This page describes the different
effects on the termites :

a.. Premise kills termites, draining the colony's strength. Other
termiticides only create barriers that repel termites, so they live to
attack another day.
b.. Premise has no odor and takes less chemical active ingredient to do the
job - up to 20 times less! So, Premise poses a low risk to your family, your
pets, your home, and the environment around you.
c.. Premise causes a range of effects in termites: they stop feeding and are
unable to maintain their colony. A second effect, exclusive to Premise, is
called Premise Plus Nature™. This phenomenon makes termites susceptible to
infection by naturally occurring organisms. Either way, the termites die,
and your home is protected!
d.. Thanks to an exclusive process called Lateral Soil Movement™ (LSM),
Premise spreads in all directions helping ensure thorough soil coverage so
termites die when they attempt to get through.
e.. Premise distributes throughout the soil creating a thorough Treated
Zone™. When termites encounter the Premise Treated Zone, they immediately
stop feeding, and your house is protected.

At the same time of the use of Gaucho, we have observed, here in Europe,
symptoms like very poor harvest of honey, or collapse of colonies after
foraging sunflowers whose  seeds had been treated with Gaucho.  Don't think
it is troubling ?
