Hired KEO to take care of bats (they are a problem in Hiddenbrooke neighborhood) nesting under roof tiles and window shutters. We initially thought we had mice because of droppings but they did great job explaining bat presence by the type of droppings, sealing the areas with foam and placing a temporary one way cone to allow them to leave before coming back to reseal. Jake A and Allan M were great. Highly recommend these guys to take care of your pest control needs. Support a local family owned business.

I honestly never do Yelp reviews, but I have to give a huge shout out to Jake! He's been working with our family and on our house for over a year and he has gone over and above for us on numerous occasions. I recently had a carpet beetle bug problem and once I called Jake, he was out an hour later to spray! He followed up with me to confirm they were gone and they were! We've add rats etc and he's always been there. So nice to know we can count on him and his team especially when we have two babies under two! Thank you JAKE!!!

I run Facilities for a food service chain (14+ locations) and so happy to have found Walter A. When I first met Walter, we had a pest control partner so couldn't give him all our accounts but one by one, as we opened new locations, he earned our trust over time in being reliable, responsive and personalized service. He now manages half of our locations in the Bay Area! He really cares about about his job and it shows in his communication and the way he handles his job. Would highly recommend him to anyone to get the job done.
