best way to kill aphids?

i have little aphids that i just began to spray for in my 4th week of flowering, im using a good organic pesticide but i was wondering if anyone knows of a better way to get rid of these pests? would ladybugs take em out quick? & what store sells ladybugs?

I'm looking into the same thing... I'm 6+ weeks into flowering. Nice buds coming in and have an infestation of aphids or spider mites It seems most of the other posts on the subject are recommending dish soap mix sprayed on when the sun is off. I also picked up something from "Bayer" that is supposed to help prevent/kill all kinds of insects. Problem is my 3 girls look so good I'd hate to kill them off by using too much of whatever the treatment is. Unfortunately I have to do something. I'm going to try the dishsoap first on one of the 3 and wait 5 days and if its effective try it on the others (I guess!). Good luck!

yes ladybirds/ladybugs are killer.. most garden centres can order them if you ask. Say your greenhouse is full of bugs eating your tomatoes. I personally never like to nuke (spray), especially during flowering. Saddam does not endorse chemical weapons. Release the Ladybirds or Lacewing larvae and watch battle commence.

If you live in UK.. Ladybird Larvae (approx.30) Treats 5 sq.m £9.99. just google 'buy ladybird larva' hope this stops you putting fairy liquid on your fruits. it tastes nasty
