Spiders
Report
Nothing gives people the heebie-jeebies quite like a big creepy spider. With our comprehensive pest control service program, dangerous spiders like the Black Widow will be long gone.
Roaches
Report
Some pests are merely annoying. Others may sting or bite. A few even cause structural damage. Then there's the cockroach. A filthy, germ ridden, nasty little insect capable of shutting down a restaurant, irritating asthma sufferers, spreading sickness and bacteria, and making even a starving man consider turning down a meal.
Ants
Report

Whether you are dealing with Argentine ants, Odorous house ants, Pavement ants, Fire ants, Harvester ants, or Field ants, we have the solution to your problem!

Love my service tech, Markus! We are a new client in Oakdale. He explained everything so well when setting us up for service. But he was really great on our first service walkthrough - he was familiar with the property but checked for problem areas, suggested some service that would help keep our home free of pests and gave us some extra tips. He didn't rush, listened to all our concerns and explained exactly what he was going to be doing.

His communication before the first service was great, letting me know when our account was set up, was the charges were going to be and when our service would start. Loved getting a text message confirming date and window of time that the service would be scheduled so I can make sure my dog is out of the way and safe! Excellent service so far and looking forward to being a long-term client of Insect IQ.

Great job today! Our home is somewhat infested with black widows spiders. Zach was the best terminator for the job. Now my family can have a peace of mind! Thank you Zach and Insect IQ for your services!

I've been using Insect IQ for 4+ years. They've always been super reliable, friendly and honest. There is many wonderful technicians but Eddie Esparza is my absolute favorite. He is really friendly, quick and THOROUGH and makes sure every inch of my property has been properly taken care of. The office staff and rest of on-site technicians equally as wonderful. Definitely recommend them 110%!

The exterminator Dalton was very respectful of my time and my home, he was able to remove all the webs from the exterior of my home and sprayed out and inside. Would definitely recommend! 10/10 Services: Spider extermination, Ant extermination, General pest inspection

I am always pleased after every visit. Since i started this service i have had no issues with bugs in and out side of home. The service at customer Service area is always helpful with my calls. My exterminator Derrick has been such a great help goes through every area of my home and answers all my questions and follows through on getting them answered and done. I recommend him and this company you will be glad you made that call.'

Insect IQ sprays a lot of product which controls the ant problem I had. Roaches and other bugs are virtually gone too. I learned over time a consistent bimonthly spray is best program. Only spraying couple times a year let's my neighbors bugs creep back into my property. Bimonthly spraying is required to control my insects as well the neighbor's bugs that are always on the March spreading into my property.

The technician that generally services my house is fantastic. He is extremely polite and literally on time, every time. Since I have been using Insect IQ, every tech that has been to my house has been awesome. I have had them since 2019 and over time, the amount of bugs I see have dramatically reduced. I was always quite concerned about Black Widows and because day 1 at my house my son almost ran into the goliath of black widows.

I really can't say enough good things about them. Super great team of techs. I am also in the customer service industry and I am more than happy to continue using these guys.

My Technician, Zach is great. He is professional, explains what was done, what was used. He always let's me know when he is done in the garage so I can close the door and when he is done with the service. Thanks Zach! Services: Rodents, Ants, Spiders

We just re-started our service after purchasing a new home in an adjacent county. Our technician Derrick was very professional, helpful and courteous and answered all of my questions regarding an ant issue. We will request that he service our account on a regular basis. The office staff does a great job also.

I have been using Insect IQ for about 3 years now and have never cancelled my regular scheduled pest control services - because I've been happy. I am a realist, and understand I will still have occasional ants or other issues, but anytime I've called them to let them know there's an issue - they always send someone out same day or next day to get it under control.

Their staff is always so friendly and knowledgeable. They also have respected my boundaries to not spray around my dog run, to keep my animals safe. I recommend Insect IQ to anyone, and definitely recommend going with a regularly scheduled service over a one-time thing. Thanks Insect IQ!

I can't say enough about Insect IQ. I recommend them to anyone and everyone I know! Brianna in the office is always responsive and addresses any questions or needs we have in a timely manner. We recently had a mite issue with our pup who unfortunately brought them back home from a hike and Brianna got on it RIGHT AWAY! Literally drove to our house to collect a sample so that they could be sure to address the issue correctly. David Sanchez who is our regular technician came out the very next day and gave us all of the confidence that we would be taken care of. We love these guys and I can't say enough good things about them. Look no further for your pest control needs than Insect IQ!

Insect IQ is totally awesome. We had them first at a house we were renting. They helped us deal with more than just insects. When we found mice in our garage, they mentioned they have services to fight mice as well. We paid for a couple of traps, they explained how they worked and checked them every visit. When we were finally able to buy our own house we were so satisfied that we carried Insect IQ to our new address.

Same GREAT service. This is where we met Tony. After one visit I knew I wanted Tony all the time. He is friendly and professional and carefully explains what he is doing every time he stops by. I called Insect IQ and asked that Tony be our permanent agent from now on. They said no problem. If you are in need of pest service Insect IQ is definitely the one you want to call. You will not be disappointed.

I have been using Insect IQ for years now and am consistently satisfied with their service, on many levels. The office staff AND the techs who come to my home are always professional, accommodating and unparalleled with their attention to detail. When I talk with my friends we are realizing that various critters are an issue more than ever this year. Nonetheless, Insect IQ is always attentive to my requests for interim sprays and that is invaluable! I also appreciate that I feel 100% confident in this company as a whole to give my garage code to the tech so they can spray in my absence! Thanks guys!

Danny was super friendly, cheerful, on time and greeted all of us! He was a delight to chat with and we requested to have him as our regular! He asked us about our concern areas and what we were experiencing in terms of pests. The customer service desk associate named Brianna is also very pleasant and helpful. She also sends out text messages for reminders of appointments and helped me set up the service all online. Overall we're really happy with the service and plan to continue with it. We hope the employees are happy and taken care of here.

Insect IQ has always addressed my needs. I have been with this company for a few years now and I have yet to find any issues to complain about. At one time I was an employee of two other pest control companies. I worked in sales and as a technician for a while but I would not use either of them now.

As a first time home owner, I wanted the best pest control defense there was and insect iq is it! I enjoy knowing my home is pest free and web free, I also enjoy the fact that I can trust them to enter my home and not need to worry! Not only did I sign my house up but I also signed my parents house up and they are just as content as I am! Don't hesitate to call them, they're always on top of their game when it comes to responding!

My parents recommended Insect IQ to me when we bought our home. I've been with them ever since and couldn't be any more happy with there services. They are always so friendly and helpful. There have been a couple times I've had to change my appointment and they never fail to accommodate us and are so willing to help every time. Customer service is amazing as well.

We always request Mong for our services as my parents also recommended to request him and he does a phenomenal job every time! I will defiantly be recommending Insect IQ to anyone looking for pest control!

We bought our home back in August 2020. Soon after moving in, we secured Insect IQ. We immediately noticed that every single creepy crawler was gone on day one! We recently obtained Insect IQ for a few critters here and there. Mainly spiders! We will continue using this company because of their professionalism and quality of work. Every six months would make us happy. And our mini Yorkie won't have to chase earwigs, spiders, and roaches to eat. Yukkkk

My boyfriend & i are first time homeowners and was recommended insect iq. we had a really bad bug problem in the beginning since our home wasn't lived in & our neighbors do not get pest control treatments. we had them come out in between services to get the bugs under control. insect iq worked with us and our issues & we are now living in our home bug free! david s. was our technician yesterday. he was so professional, easy to talk to, & answered all of my questions concerning the safety of our puppy. insect iq also sends out a very informative email stating all of the products used. for my own peace of mind i researched the products and discovered insect iq uses all eco friendly and natural products that are safe for people & pets! i love that my family & my puppy is safe from chemicals and nasty bugs.

Omgosh! Tony is the nicest guy ever! I hit the jackpot when we get Tony, all jokes aside he is just super nice, friendly and knowledgeable! And actually cares to make my kids and my self feel comfortable again and not have to be worried about any spiders coming to give us bug bites. My 15 year old was bit but we don't know by what her room was clean! Couldn't find anything!

But just to be sure and put our mind at ease he still took the time to spray under her mattress and all around in and under bed, we took the whole thing apart! WOW he's so Great! THANKS TONY!.now we don't have to worry!

Awesome company. They're always very professional, friendly, and responsive. We had a mild recurrence of insects after one of their treatments, and they came out again immediately to re-spray and fix it free of charge. You can tell they take pride in their work! Would highly recommend to everyone.

I was referred to this company from a friend. I had plans to call many different companies throughout Modesto to get the best price, BUT when I hung up the phone with one of their employees named Priscilla, I knew I was going to chose this company. I'm still in awe and admiration for the exceptional customer service that she provided. I had about 50 questions and not only did she answer each one with such a pleasant voice, but she gave me even more information that I didn't know about what a Pest Control company can do for me.

Just interacting with Priscilla alone, is enough to get 4 stars. She's the first person that i spoke with, that represented this company, and she has represented the company well! Now the quality of the services is 5 stars! I have dealt with the technician named David S. He ALWAYS has a smile on his face and answers any questions I have. He cleans the webs off of the exterior and hasn't missed any webs. He's EXTREMELY thorough in every service and patient as I try to get my dogs inside/outside the house so he can continue. I've noticed that I no longer have any pests inside the house nor outside with just the first service.

Every time he finishes spraying the house, I noticed that he gets every corner and inch of the property. I haven't dealt with the other technicians but interacting with Priscilla and David S has made this a company that I will forever recommend to anyone!

Without Question the best insect and rodent control company I have ever used! I'm a recent transplant from LA to Modesto, and our house was over run with rats the size of Yorkies! A tech came out and after our first visit, the problem was nearly eliminated! I signed up for a service contract and this visit really prompted me to write about Insect IQ!

Service is Amazing! Tony is a rock star! Best service ever! Took care of all of our needs, understood and was able to come up with a creative baiting solution for our rodent problem! I'm really grateful for the extra step service and will be recommending InsectIQ to everyone I know!

Their guy broke 2 pots, sprayed a cloud of fumigant in front of me as I was walking inside with groceries, which I inhaled & got all over my clothes. He even sprayed the doorknob just before I walked inside. I don't think I'll use them again.

I normally do not write reviews, but today I felt I had to. I have been using Insect IQ for a couple of years, I called and asked them to treat my sister's home for infested roaches, they worked with me and did the service and today she has no roaches, this was amazing to me.

I woke up to find ants invading every room, my hallway, pantry, entryway and outside all over my dog's food. I called to see if I could get someone asap and insect iq was able to send someone out same day for an estimate and spray.

I have been very happy with Insect IQ for my home pest control service. They always call me a few days before with a friendly reminder of my service date. Yesterday, my usual service technician, Howard, really went above and beyond.

Amazing service! Family owned and it shows. The entire crew at Insect IQ are friendly, honest, professional, and most of all they know pests! I have a business in downtown Modesto and the roaches and spiders are a big problem for everyone.
