Hi Brian, I was thinking of the spray type ozone stuff.

He knows what chemicals and sprays to use depending on the situation, whether it's cat urine, nicotine, etc.Good luck.

I know a lot of people carry pepper spray but definitely don't want to have just that if they have something more devious planned.

I would at least show an effort and keep the receipts for bug bombs, ant/roach spray, d-con mouse/rat poison, insect granules, professional carpet cleaning. 

Not making rounds to collect cash rent, not being in the house while prospective tenants are, pepper spray, maybe I'm just overly concerned about not putting myself in potential harms way.Your tagging doesn't seem to be working.  

Before laying new tiles, do you recommend to spray termite chemical?

The bigger question is how effective the "spray and pray" approach to offers is...answer: it's somewhat market dependent, but for the most part it's a waste of yours and everyone else's time. 

- Up-front cost difference- Energy (heating) costs- Comfort- Resale value impact- Anything else that's relevantWhen I say crawl space, I mean a non-ventilated, moisture-protected (vapor barrier, waterproof spray, and sand/gravel), heated space, NOT the dirt-covered, ventilated space of old.Thanks!

Get some rmr-86 and get your handy man to spray it.

One of the Bedroom windows is slightly damaged, so I think a spray and slight repair will be enough.
