Hand-picking
For insects that don’t overwhelm by the hundreds (such as aphids!), hand-picking can be a very effective, simple and FREE organic pest control method.
All it involves is removing the troublesome insects from the plants… and you can wear gloves if you’re feeling squeamish, or just clip off the branch that the bug is on.
But don’t drop the insect onto the ground, or the branch they were on. You need to dispatch them.
I’ve had great luck with carrying along a container of soapy water (see photo) and knocking the insect into it. You would be amazed at how well this works!
