Dewey Pest Control Pasadena Reviews: Fumigations & Flat Fees (2026)

Last Updated: 2026 | Data verified by The PCC Research Team

In the San Gabriel Valley, you cannot treat a sprawling historic home the same way you treat a newly built townhome. When it comes to massive jobs—like structural fumigation or heavy wildlife trapping—homeowners often turn to large corporate brands like Dewey Pest & Termite Control.

As part of our comprehensive Pasadena pest control guide, we constantly monitor the performance of the region’s largest operators. We bypassed the corporate brochures and audited raw, verified Google Maps data from homeowners across Pasadena to see how Dewey actually performs in the field.

What our 2026 data extraction revealed is a highly polarized branch. If you need honest termite inspections, subterranean treatments, or routine insect defense, Dewey’s local field technicians are elite. However, if you need outdoor yard services (like gopher or mole trapping), their flat-fee pricing models have led to severe disputes. For anyone searching the best pest control companies in Pasadena, here is the verifiable truth about what to expect.

Service Deep Dive: Elite Termite Honesty & Quality

In the pest control industry, it is incredibly common for aggressive salesmen to mistake flying ants for termite swarmers in order to sell a $3,000 fumigation. As detailed in our head-to-head termite guides, identifying the exact species is critical.

Our data shows that Dewey’s termite division in Pasadena operates with absolute integrity. They do not utilize scare tactics, and when a large job (like a whole-home tenting) is actually required, they execute it flawlessly.

• “Brian called me at work and was able to determine from our conversation within minutes that I did not have a termite issue. To be thorough, he asked that I send him pictures of the bugs that we had caught. He confirmed his assessment with another expert at his company and assured us that the insects were flying ants and of no danger to my family or the house. It’s rare for me to find a person and or business these days with such professionalism and patience.” — Eugene Hsu

• “Brian at Dewey was great – it was our first time fumigating our home and he walked us through everything. A little bit pricier than other quotes we got but they used more gas and did a much more thorough job under the house with the subterranean termites. They were able to do the job on short notice and everything went smoothly.” — Bill Robinson

Service Deep Dive: General Pests & Wildlife Control

For standard residential route work, Dewey’s technicians receive high marks for consistency. They are highly rated for quarterly maintenance programs and for dealing with larger, nuisance wildlife unique to the SGV foothills.

• “Highly recommend! I was dealing with a decent amount of normal house pests (spiders, earwigs, silverfish, etc) as there are a lot of plants in my area and my unit is older. Omar has taken care of this for me and more! … I have a quarterly plan and it is definitely worth it. I went from finding sometimes several bugs inside my house each day to maybe one or two per month.” — Corinne Fortunato

• “We recently had the pleasure of working with Dewey Pest Control, and I can’t say enough good things about the technician assigned to our property, Daryl Quintana. He demonstrated exceptional expertise in addressing a rodent issue in our garage and provided invaluable suggestions for managing the moles and gophers in our yard.” — MICHAEL GOBLOWSKY

The Bad: Gopher Pricing & Careless Inspections

To provide absolute transparency, our audit also isolates the negative reviews. The data shows that while Dewey handles structural jobs well, their outdoor yard/gopher trapping is prone to flat-fee pricing disputes. We also uncovered a concerning report of a technician damaging a window frame during an unapproved inspection.

• “They are irresponsible and don’t know how to deal with pet control! My front yards have gophers and mess up the yards… I asked him if I needed maintenance service, and he said no. As a result, I paid $500, but they only came to my house once and did not show up after three weeks… The service under the contract has not ended yet, and the ground rats are still digging holes everywhere.” — Susan Z (1-Star Rating)

  *PCC Note: Branch Manager Omar McKenzie did reply to this review attempting to resolve the issue, but homeowners should always get the exact number of included follow-up visits in writing before paying a $500 flat fee for yard trapping.

• “It’s not professional and necessary when technicians make ‘holes’ on your window frame without your permission to demonstrate possible Termites. Ask owner first. Took my business elsewhere!” — Dave C (2-Star Rating)
