Aphids on seedlings

[Psyche]

I’ve been lucky to be mostly chemical free in my garden, but I finally got a plague of aphids.

They are on my seedlings indoors.  Do I toss the lot and start over?  What should I use?  I’ve got about 3 weeks until last frost day.

I'd take a squirt bottle and try to flush them off. They should be outside already in a shady spot.

Just water?  I’ve been squishing by hand and knocking them off, but they just keep coming back.

They should be outside already in a shady spot.

Why a shady spot?  Do you mean bring them in at night so they don’t freeze at night?
