Deadbug doesn’t have a long lifespan once mixed, clean walls with a mix of peroxide and alcohol, it’ll kill anything in there, you just have to keep watch to make sure they don’t return.
I got a LED Bug-zapper as a preventive measure. Also have the Capt Jack Neem oil on the standby. You can feed your girls some Silicon as a preventative measure and use beneficial microbes to your media , soil or hydroponics, to boost prevention.
Yes this will help. ‘Anything’ you do in the peat prevention area will help in one way or another.
When I spray our plants I also always spray the exterior of the pots, top of the soil and also around the plants. Pests don’t only live in the plants instead but also every nook and cranny of the garden. (Durring an outbreak)
