Indoors or outdoors?

FataMorgana

Out side but in pots

Just wash them off with a hose or spray bottle. If you can lift the pots hold the plants under the tap and rinse. No need for weird concoctions which are more likely to cause trouble than get rid of a few greenfly. If your lemon balm is dying it is very unlikely to be caused solely by aphids. They often go for weak plants and generally just cause leaf distortion. Could you post some pictures of your herbs? It's always difficult to imagine your growing conditions.

No bother I will upload pics later but know this it is just pots on top of things I made 2 platforms from wood going to a scrap yard.... my dog kennel has wood across so I can get a platform for other things and my rosemarys are just on top of things like the oil tank and burner with what I got it all I could do really

as promised here is bay oregano and seedlings but it basic stuff which I gotta make space from noting it not perfect but when came here never once thought I would end up going at these this much

full light ones rosemary oreganos etc again no where near perfect

more rosemary trying keep thin as had problem with mildew

mints in shade only place could get them tbh

Well that set up looks fine to me although some of the pots look a little small. And why do you have them all up on things rather than on the ground? I think they just need to be left alone for a while to get on with growing.

I got a dog it won't leave them alone he chewed a bay tree of mine rosemary and a few others lol

will m int bounce back from aphids?even if it hits root or rock bottom?
