Re: semi-OT: deterring critters in the obsy

Right, another synthetic pyrethrin.  The most effective control for hornets/yellow jackets and wasps is to catch one to two, identify the species and hang traps that have a pheromone specific for that species.  It’s pretty easy to tell the difference between them by looking at the head and abdomen banding.  A trap made some doesn’t work on all.

I do two things.  
1.  Twice per year (early Spring and early Fall) I spray an insecticide called Tempo SC Ultra on the outside walls and perimeter of my roll off roof obs.  This stuff works great, for other areas of the house too.
2.  I put a little bit of peppermint extract in a small spray bottle and once a month I spray the inside of the obs, especially around any cracks.

I haven't seen a spider in years in my obs; wasps are a completely different story.  Nothing deters those buggers.
