    I called around all the top reviewed places and decided on Original Rodent Proofing. They were…read morecompetitive, not the cheapest, but Shannon Lee sold me on their work, along with Brandon (owner's) call to check in and answer any questions. Their warranty on work done was another key factor. An electrician found a dead rat and droppings in the attic, so I needed clean up and rodent proofing. In the crawl space, a bunch of the ducts were unattached by wear and tear and plumbing work that had been done in the past (which I didn't know. No wonder my gas bill was so high over the winter!). Shannon and team cleaned everything up, sanitized, reattached the ducts and rodent proofed the whole house on the outside. Apparently the attic was vulnerable, as prior owners' foam had been chewed through in the eaves. After they were done they set traps which will be checked every few weeks. I will update if there are any further rodents but I am confident in the work by the company and team. I highly recommend this family owned company.

    Before hiring, I had asked my local mom's group, local raves and rants page and Nextdoor... these…read morefolks came up as highly recommended. So we interviewed them for the job. The guy who came out was on time, a bit eccentric and very passionate about rats. He was detail oriented and did a great job explaining the job and its breakdown. Unfortunately on the day of the job, we had 4 guys come to our home on time- but none of them spoke English. Now, I appreciate them coming out, but we just could not communicate and they did not have work trucks or shirts with their company name. An hour later, we had a younger guy show up and he spoke English. The crew worked really fast, did a nasty job of removing our rodent infested insulation and put in new insulation, they mixed concrete and patched up some holes as well and put out rat traps. They came back twice to check the traps and removed them. I think they did a good job, appreciate their punctuality. But management should always send someone who speaks some English and provide a company truck or at least shirts. I personally felt uncomfortable letting into my home a group of random men with no identification.

With kids and pets, we prefer the ad-hoc visit over a monthly service plan and Jaime does not pressure you into a plan and does a great job solving the problem in one visit and that lasts several years. During his most recent call out, we found an area where rats had chewed through the crawlspace vent. He did an inspection and provided a very reasonable quote (compared to what our neighbors had paid to other providers). It's rare to find a reliable, quality, one-man shop - Jaime at Pestfinders is that diamond in the rough that I can't recommend enough.

First of all, on the first visit, within ten minutes, the technician had spotted an entry point on our roof that was likely the cause of our isse. It wasn't obvious and the previous service we used (one of the larger services in our area) hadn't spotted this. Another thing that I noticed was the respect and care the technician showed at our house. It's a small thing, but when the technician entered our house he noticed that we had shoes by the door and went ahead and removed his shoes when making his way to our attic. Taken all together our technician was detail oriented, respectful, and thorough. And he solved our problem. On top of this the price point was comparable or even less than the larger company that we had used previously. I would highly recommend Pestfinders to others.

    I hired All in One Pest Eliminators to deal with what appeared to be a skunk living under my house…read morein the Oakland Hills. The skunk was spraying so frequently that the odor had become overwhelming and was actually making its way into my bedroom. Living in the hills, wildlife is simply part of life. Most of the time it's one of the perks of living here. Unfortunately, this particular wildlife situation had become unbearable, so I called in the professionals. OR, what I thought were the professionals... I should have just called a Doberman. I will start by saying that the technicians themselves were professional. Unfortunately, the actual service was a complete failure and complete waste of money. They came out, set a trap, filled it with cat food, covered it with a bag, and instructed me to check it every morning. The problem with that approach is obvious: if the trap actually contained a skunk, the only way to find out was to walk right up to it and look inside. Nothing says "professional wildlife management" quite like asking the homeowner to potentially get skunked. Over the course of the next week, I was repeatedly assured that the bait being used was specifically designed to attract skunks and that possums supposedly weren't interested in it. Yet somehow, the trap managed to catch three possums and exactly zero skunks. ZERO SKUNKS! The skunk that was actually causing the problem remained comfortably under my house, probably laughing at them and apparently completely unimpressed by their "specialized" bait. Meanwhile, the charges kept appearing on my credit card. By the end of this adventure, I was out roughly $700 and left with the exact same problem I started with. Three possums had been trapped and removed--none of which were bothering me in the first place--I honestly feel bad for these poor possums, what did they do with them when they took them away? While the skunk continued living its best life beneath my home. Three possums later, I'm convinced the trap's only qualification was "contains animal." I'm honestly surprised they didn't catch my own cat, a squirrel, and the neighbor's golden retriever while they were at it. The skunk, meanwhile, continues to live its best life under my house while I funded this expensive wildlife exchange program. Thank you All-in-One. If your goal is to spend hundreds of dollars catching harmless possums, this company may be for you. If your goal is to solve a skunk problem, All N One Pest Eliminators are a COMPLETE WASTE OF MONEY!

    Highly recommend Mr. Attic - Rodent Proofing & Insulation Services!…read more I contacted them for an estimate, and Sean was able to come out quickly to inspect both our attic and crawl space. What really impressed me was his honesty. After checking everything, he told us that the attic looked fine and that our crawl space was dry and in good condition. He specifically told us there was no need to spend money on work that wasn't necessary. Some contractors might recommend extra work just to make money, but Sean was completely honest and straightforward. He even came out and did the inspection for free, even though there ended up being no work for him to charge us for. It's not easy to find this kind of honesty and professionalism. Sean was quick, knowledgeable, and trustworthy. I really appreciate that he put the homeowner's best interest first instead of trying to make a sale. I will definitely call Mr. Attic again if I ever need attic, crawl space, insulation, or rodent-proofing work in the future. Thank you, Sean!

They worked with us to customize their work to our coastal climate and were very transparent about exactly what materials they would be using (all top of the line, industral-grade!). I have pets and toddlers and they took my concerns about chemical disinfects seriously and offered several options to make sure I was comfortable with what was used in our home. They really seem to take pride in their work and enjoyed sharing before and after pictures to demonstrate all the improvements they made to our crawl space. I could not be happier with my choice to hire them, and plan to work with them again when I'm ready to replace my attic insulation.
