We found that Arabidopsis responded poorly to a number of insecticides, possibly due to the sticky residue left on the plants (wetting agents?), and for greenhouse plants we ended up using a pyrethrum spray from an aerosol can.

We just use a mite bomb... we set one off every 2-3 weeks and that
seems to keep the insects (all of them) at bay... we set it off before
we go home with the aircon switched off and vents closed and the first
person to come in in the morning switches everything back on. We have
never had any issues with plant growth.
