You might already know but that smell actually attracts more of them. In your case spraying insecticide sounds like it would be more effective and a lot less work.Down here in Florida I am being taken over by them. Every day I go out with my gloves and squash tons of them. Does not even put a dent on the population. Did you know a single stink bug can live 2 or 3 years. I now like the smell of dead stink bug. lOL Damn them
These stinkbugs have showed up in Mississippi this year too, along with the brown stink bug, not very many green ones this year. The 2 week interval of spraying with neem on the interior of the plants with modified a spray wand (spray directed upward) has worked wonders on the tomato crop this season. Peppers are starting to come in and with very minimal stink bug
