It depends on what the active ingredient is, and application concentration.

I am not familiar with the US brands, but work professionally with pesticides so a checked a couple of things for you.
Ortho Sevin works based on Carbaryl. Green light tree and shrub works based on Imidacloprid. It is safe for ornamentals according to the company, but it doesn't seem to list mites.
A better option in the Green light range seem to be Conquest or Neem (last one is organic).

The label should say it is an insecticide suitable for ornamentals.

In the US Bayer Advanced Rose and Flower Insect Killer is the systemic Imidacloprid with a pyrethriod. I've used this without harm on Sarracenia, Drosera, Utricularia and Dionaea. This comes in a ready to use spray bottle.
Bayer Advanced Complete Insect Killer is a concentrate (mix your own) but there appears to be two formulations - get the one with Imidacloprid - it's the same as the Rose and Flower just concentrated. The concentrated Tree and Shrub Insect Killer has Imidacloprid but in a higher concentration than any of the above. You can do the math and dilute it to the same concentration.
Rose and Flower Insect Killer works well against aphids.

Only time will tell. If you bothered to go to the Bayer Advanced website and looked at the product label for their Rose and Flower Insect Killer you'd see the Imidacloprid concentration is 0.012%.
From my calculations you'd need 1.32 ml of your 9.1% to make 1 litre of 0.012% solution. Thus the solution you used was roughly three times the concentration that of Bayer's.
And it's the inactive ingredients which will usually give you grief.

I know this will probably make some people cringe, but I've used Systemic Insect Killer from Ortho ( formerly Isotox ) on my collection of Sarracenias and flytraps with no bad effects - make sure you follow the application instructions, use latex gloves - I usually only spray once in early spring right after divivding and growth begins, for aphids and then again, if needed in summer for mealybugs/scale in the crowns and leaves of Sarracenias, ONLY IN THE EVENING OR EARLY AM when it's not going to be 102 + degrees - DON'T overuse as not only can it harm your plants if made too strong, but pests CAN build up a resistance to it - it also smells really bad, but I dont like constantly spraying my collection - I've done this now for @10 years

Just curious: is there any bad affect if the sprayed chemical flows into the soil or the water in your tray (if you use the tray method)?

It should not be a problem if you are using the recommended concentrations. If anything the systemic will be taken up by the roots be more evenly distributed throughout the plant tissue.
And better to end up in your tray than into the water table or sewer.

There are other things that will work for all the other bugs. You can't find acephate any more and that was good stuff. I think the EPA banned it's use.
