We have had Dewey Pest Control service for over 20 years. They’re great and it makes a huge difference year round in the amount of pests we see around (or in) our house. I recommend them! Joe, our service rep, makes all the difference. He is friendly, helpful, and professional.

We’ve been satisfied Dewey clients for quite some time with steady responsible personnel. With Covid came change, a new inspector / technician. Joshua, like his predecessor., visits regularly, gives us advance notice and helped address a specific ant issue that suddenly cropped up. The steady value continues: I highly recommend Dewey and if you are lucky, maybe you’ll get Joshua.

As a property manager with 30 properties and 285 dwellings throughout San Diego County it important to work with good vendors. This San Marcos location is better than good, and the manager Jayson is responsive and attentive. Also at this location is a tech named Josh who is courteous, professional, informative and helpful. Josh was asked to call me regarding a rodent issue which he did and not only did Josh explain what was going on in a dwelling but on the exterior as well. Thanks so much Josh and congratulations Jayson for having such a valuable person on your team.

We have been using Dewey Pest Control for over 20 years, 18 in this home. David is our current service provider and he is wonderful! He's always careful to call ahead, making sure our dogs are put away while he works. He asks what, if anything, he should be aware of that might be new that he needs to treat for. If anything does show up mid-month, he's quick to come out and re-treat. He's thorough, respectful and kind. I highly recommend their services.

Oscar is kind, considerate and gives me a heads up before he comes every month as I'd asked him to do. He is thorough and helpful. I have not had ant problems for years!
