For fungus gnats, I thought these traps were supposed to be great for monitoring but not really effective for control?
For fungus gnats you might catch some of the adult flies but it is the larvae in the soil that do the damage.
To interupt their lifecycle you'd have to catch all the adults before they lay eggs and a single female can
lay a lot (hundreds to thousands) of eggs. So in practice traps would need to be very efficient to give good control?

Can someone please explain the point of catching and killing harmless insects?

Mealy bugs maybe so, but all others - no.

We should be helping them thrive, not killing them.

Millions of citizens walk about daily killing billions of micro organisms and insects under foot, that's life. To provide food for us farmers need to control that which seeks to destroy crops. As a realist and not being a woke or a snowflake I accept there's only so much we can do to protect wild life in all its wonderful forms.. However I respect your right to ask the question.
