I plan on getting it resolved as soon as I can, but I'm looking for insight into whether the best course of action would be to call in an exterminator now, vs taking care of it myself, which is how I've always gotten it done in the past.My tenants leaves food for her cat every morning, and has found ants crawling over the cat food for the third time in two weeks.

Welcome to BP it's more than a web site it's more like a team whit 1 goal and different ways of obtaining !!

But on the POF letter theres contact info with an office address and web site.

Is there a web site or even a tool on Bigger Pockets to be able to figure that out? 

There are many others that can be found through a web search or on Meetup.com.These are a good place to meet other local investors and vendors.Good Luck!

So I am assuming these properties are not in distress (foreclosure, REO, short sale), so what would be the motivation of selling a property in the web site (or what would be a buyer's motivation to buy such a property instead of just buying a non-auction property which can be inspected)? 

Do a web search, find some meetings and meet some people.
