Our Specialties


Mice/Rodent Control

Rodents enter our homes looking for warmth and food. They bring disease and multiply rapidly. R & D Termite and Pest Control will determine the best solution to get the rodents out of your home and make sure they never come back.



Spiders are exceptionally numerous and adventurous in our local area. We have years of experience controlling these potentially dangerous pests. Call today for a free consultation.



Ants are everywhere in our area and over the years we've seen it all. We'll identify the best solution for your particular situation, enabling you to enjoy your home without undue worry.



Termites can cause severe structural damage to your property. We will inspect your home for signs of termite infestations. If an infestation is discovered, we will determine the best course of action in order to remove the termites and protect your property for the future.


Cockroaches and More!

We offer a range of other services to manage troublesome pests! We control bees, wasps, fleas, earwigs, cockroaches and more. Call today for a free consultation! (707) 320-1277

Trish S.

I think Rio Vista is one big ant hill!!  We use R&D Pest Control.  They live in Trilogy and are very nice people.  They help with other pests, as well.

Jane S.

I'm so happy! I was able to do some minor yard work this morning without any creepy biting things crawling on me. Thank you R&D Termite and Pest Control.

Warren R.

Another VERY STRONG recommendation for Ron at R&D Termite & Pest Control. We thought we found signs of termites, Ron came out today and after extensive, thorough checking around the house confirmed we didn't have a termite problem and made no effort to "up-sell" us to some other service his company offers. He refused to take our offer of payment for his time spent here with us... truly an honest, local businessman.

Jackie W.

A great couple who live in Trilogy. They do their regular service well and they came out quickly for a problem we had. We don't have any problems since we invited them to take care of our home.
