When using dust, to keep the bugs away, what is the standard procedure. Do you have to wait 7-10 days until you can eat the veges again. I know you only apply every 7-10 days.
Can the dust simply be washed away, and we continue to eat our lettuce ?
The product used was “Yates Derris Dust.”
I have read all the info on the product and research online.

Hi Bryce
Thanks for your question. Yes Derris dust if that is what you are using is best to have a 7 day hold between using the produce. You probably don’t need it use it on your lettuces or could try Neem oil as that has no holding period and works for sucking and chewing insects.
Happy gardening
