I released Aphid wasps Years ago,haven't seen an Aphid since then .
A couple Mummies,but no Aphids.
To me,Aphids spread diseases/Fungus and other nasties Or just weaken a plant.
I think , main thing is the juice they put out is the main problem,then once 1 plant gets sick from Whatever,you are screwerd.
Especially indoors-it spreads Fast as they spread out,the aphids.
Soaps etc. never worked well for me.
Only killed a majority not enough to get rid of the Aphids.
I use Terro brand Ant Bait too at the same time.
I use soda bottle tops to put the bait in wherever I see ants farming Aphids.
Haven't seen an Ant in my garden in years Either.
Lots in other places,just not in my pots.
No Aphids to farm,no reason to mess with my plants anymore...
I don't use poisons at all.
Nematodes-natural stuff in general.
Neem never worked very well,soap sprays were the same.
Good guys are Set it and Forget it type thing.
When food runs out they go elsewhere,But always a few come back to check things out I think.
Green Lacewings are the best for general nasty bug control.
I don't know why Ladybugs are so popular.
Not into eating as many nasty guys as Lacewing Larva-in my opinion.
Lacewings don't do well indoors.
Neither do Ladybugs in my experience,so far.
Adults need Pollen to lay eggs.
I find them dead in my windows,trying to go outside.
Same with Syrphid Flies or other stuff.
They are natural here.
Lots of buds bring them around-adults.
We called them Sweat Bees.

Now Mites,other than Red Spider mites are REAL nasty.
Red Spiders are easy to kill,other forms Suck big time!
Broad mites and other types of spider mites sucked.
Only way I Might have gotten rid of Broad mites was when my garden died during Cancer treatment-Garden died.
They LOVED my C.Pubescens.
I had several Large Heavy producers.
See U.C. Davis info on pest control.
See Canola oil as being better than Poisons,Soaps etc.
From experience,You Have to Constantly shake the mixture up as you spray it or the last stuff that My 2 gal. sprayer put out was mostly oil.
I got Lazy and since I was Almost through spraying,I didn't shake my sprayer as much.
Wrong thing to do-Last plants I sprayed were Oil or soap killed.
My Fault...
Killed off a few plants.
Sun and oil don't work.
But it did seem to get rid of Broad mites pretty well.
Also Sulfur seems to work too.
But is hard to use.
Sun , Water and Sulfur make Sulferic Acid.
I had to spray at Sundown and hope it dried before sunrise in winter.
Also,it seems different plants don't like it(Safer brand-WELL shaken fungucide) was what I used.
I grow in pots year round,take my suggestions as just that.
Hope this helps you out.
Smoke
PS.
Some Varieties are less strong to stuff than others.Plant to plant,My Grow VS. Your grow could very well be a Lot different.
As I said,hope it helps you out or just gives you something to mess with for Your grow.
Keep us posted as far as what works or doesn't for your grow.
I gotta say,I loved watching Aphid Wasps coming out of the bottle to my Heavily infested plants years ago.
Revenge is sweet. LOL
It was like a Cartoon when a character nocks down a bee hive.
Bees make a Bee line to the characters behind...
Watching the wasps do their thing was good entertainment.
I have to admit,I never thought the videos were 100% true.
They are!
They don't get into being bugs flying around your house.
They must find a way out.
Unlike other good guys,I've Never seen dead ones in window sills or flying very far from my plants.
Very small critters.
