We are not a big company that you have to go through all the phone calls. Owner Andy Zhang will be the one to answer the phone, provide you the bid, and supervise and inspect the work before finish. We are so confident in our work, quality, and over all experience that we don't need any money down. Our customers don't pay us anything until the work is done and customer is happy!

Stop Bugging Me Pest Control is a locally owned and operated service company located in Seattle WA. We offer guaranteed pest control solutions for residential and commercial customers in the greater Puget Sound.

Our staff will take your call and work with you to first identify the problem.

When the technician arrives, he will discuss strategies and follow our exclusive programs to eliminate the problem and leave you with useful recommendations for future control.

"The MOST UNPROFESSIONAL SERVICE CALL, EVER! A twenty-something, long dark-haired guy showed up (no name, as he wouldn’t give it to me). He came in, asked me where the ant problem was. I showed him the trail, collection and path. I told him that I was recovering from pneumonia and didn’t have much voice left, so to “bear with me.” He walked away and told me that he disagrees with me. I questioned, “what do you mean? Why would you be contrary, while I’m telling you our issue-the townhouse neighbor and us, have been passing the ants, back and forth, for 7 years. He told me I was wrong, and they all just hatched. I responded that we had treated our home for ants FOUR times, in the last 6 months. When showing him the area where we saw an ant hill, he was belligerent and condescending, asking me, “is it an ant hill or just a few ants?” I told him I was from the country and knew what an ant hill and ants looked like. This is where it went terribly disrespectful, condescending and offensive. He asked me, “so what kind of ants are these?” I responded, “beg your pardon? They are obviously sugar ants. Why am I being asked that?” He then smirked and said, “how do you know they are sugar ants? How can you tell?” I told him that I didn’t appreciate being called a liar, with regard to our issue and tested, as to my knowledge of ants. He responded, “well, you’re the expert!” I could not believe what I was hearing! Who was this person, to come into my home and disrespect me, in such a manner? I wonder if his behavior would have been the same, if it were my husband, he was dealing with. Every time I attempted to speak and explain our insect issue, he would interrupt me, with a rude and contrary statement. He pulled out our kitchen counter items, spotting a busy ant area. He began to spritz the area. I explained that the connected unit would get ants in their kitchen and within hours, I had them in my kitchen and back and forth we went. He dismissively questioned my honesty in stating that he questioned that happening. Again, I was so offended, I wanted to cry. On top of being sick, I had this guy insulting me, in my home! I told him there were also ants in the living and offered to show him where they were, he said, “nope, don’t need to see it.” What? I said to him, I’m not sure what’s going on here, but I don’t appreciate your continued insulting and interruption, when I am sick and trying to get this problem rectified. He, again, insulted me in saying, “well, I know I was out here a few times, and you wouldn’t let us in your place.” I responded, “I have never met you, nor have I ever requested pest services and denied entry. You are literally making that up and you know it.” He smirked and said argumentatively, “well, I’m sure it was you.” I told him, “I don’t appreciate you making up stories, in order to somehow justify that this ant problem has not been rectified. It’s completely inappropriate and unprofessional.” He again smirked. At this point, I told him, “Please just get this handled. I’m very sick and need to lie down.” The most shocking and unprofessional behavior yet? Here it comes…he picked up his bag, walked to the front door and said, “I’m leaving. Your grouchy and rude and let me know when you’re in a better mood and I may come back. Good God, I felt like I was in the twilight zone. I said to him, “this is ridiculous. You don’t get to tear my kitchen apart and then leave, without doing the job? No one is giving you a hard time. What is the matter with you?” He walked out the door. I asked after him, “can you at least leave the ant traps?” He did not even both to turn around and said, “Nope! I didn’t even bring em’.” Wow! He sat out in his truck, for 25 minutes, before pulling off. I am contacting the BBB, the complex management, where we live, and the company owner. The behavior of this pest control representative, made this 59 year old, sick woman, feel disrespected, insulted, discriminated against and verbally abused. This type of behavior, especially inside someone’s home, where you are a guest, cannot happen. I’m not generally intimidated, but felt very unsafe, with this pest guy. It is now the middle of the night, and, with pneumonia, I had to clean up the ants and disinfect the area, that he left unattended, and still have ants, all over my kitchen. Absolutely unprofessional and unacceptable. I am sure your company does not advocate for this type of black mark on your reputation and look forward to hearing from you regarding this unprofessional experience."

"At every step along the way they were thorough and professional. The estimator provided a very detailed scope and quote and patiently answered my questions. The installation crew was quick, efficient, friendly, and were so meticulous with their prep that up you couldn't even tell they were here after they left. I also appreciated the "after-photos" they sent me, it looks great!"

Basement Waterproofing questions, answered by experts

It’s normally possible to stay in a house with water damage, but it depends on many factors. If the water damage is minor, like from a small plumbing or window leak, there’s minimal risk to you and your family members, especially if you catch it early. Major water damage from flooding is more likely to lead to mold growth and electrical issues, which means it’s safer to relocate until you have a professional dry out the area and treat the mold.

One handy thing about whole-house dehumidifiers is, once installed, you don’t have to worry about placement or changing the dehumidifier’s position. But if you are using a portable dehumidifier, we suggest keeping it away from walls, vents, and furniture. It needs a central, unobstructed spot with access to lots of air to do its job.

Yes, the air from a damp basement can travel up into your living area through a process called the stack effect, so moisture, mold spores, and other debris in your basement air can all decrease your indoor air quality on your main floors. Additionally, damp basements can promote the rotting of building materials, which can damage flooring, insulation, and framing on your first floor in addition to materials in the basement.

The best way to waterproof a basement is to install a properly functioning gutter system and a French drain around the outside of the foundation. The best solution for your home could involve other waterproofing methods that resolve the problem unique to your situation. Depending on your soil type, climate, and other factors, that could include sealing, landscape alteration, interior drainage systems, and more.

If a crawl space isn’t vented, there can be moisture buildup, which can lead to mold damage, easily destroying the foundation of your home. A closed-off crawl space can trap heat, which can be useful in the winter, but can also trap dangerous gases and prevent clean air from entering the home through the floorboards.
