Acetamiprid Insecticide

I have a pack with:
N1-[(6-chloro-3-pyridyl)methyl]-N2-cyano-N1-methylacetamidine
and
Acetamiprid (its systematic)
in it.

I have a whitefly infestation and have had enough Id much rather prefer
natural predators but they are not available to me. So anyway, this shit is
for tomatoes and it breaks down in soil etc i looked it up on wiki.. The shop
owner told me to put 1 teaspoon of it into 5LT of water and foliar feed.
I have put 0.64gr into 700ml of water and sprayed 2/3 of it on my 40 girls.
I checked this morning and it seems to have nuked them pretty well. Rather than
getting a cloud of flies when i brush the plant there are 1-3 per plant now.

Should i repeat this treatment for the incoming eggs to hatch etc?

Oh and i was told not to eat my "tomatoes" for 3 days xD

Legalize...

Update: 1 day has passed and my infestation has improved greatly. But they are not eradicated and i can see eggs under the leaves. I think i will need to apply again but this stuff seems to have done a great job. Anyone has any ideas on how long i should wait to apply again, pretty pleaaase? Or maybe how many days approximately to check if they are still alive and nuke? Thanks in advance

Peace out and peace in!
