I was/am/was/am striving to grow organically, but sometimes (rightly or wrongly) I feel it's futile here. Despite using organic methods, sprays, etc. once or twice a year I get these infestations and it seems like the organic approach isn't harsh enough to solve the problem. That's why, once or twice a year, I feel like I have no other choice but to turn to the stronger chemical pesticides.
The time and effort I have put into, and am still putting into, growing fruit and vegetables simply can't be in vain.
Perhaps it is taking me longer to build up a beneficial growing environment, soil fertility, etc. than I had expected.
As always, thank you for your feedback. It's very helpful.
