In an attempt to manage the flying and
wood roach population that have taken abode in the shed-house, I use diatamacous earth, and salt. Along with a knife and flashlight! I recently picked up some coarse salt and it works well in the slingshot to knock them down from the ceiling so I can then get them by hand.
I generally do not harm insects and it hasnt been very fun the last few years going after them.
All started with a pile of wood brought in, but leaving windows and doors open has now invited the flying ones in too.
Thankfully I only sleep in there when its cold (wood burner inside) and they are not as active then.
