Common Pests

"Ants, Spiders and Roaches,


Ants, spiders, roaches, bedbugs, mosquito's and more.. Otherwise known as "bugs," these are the ubiquitous "bad guys" of the pest world. They are the usual suspects we deal with all the time.  We know how to eradicate them from your life.  Call Gateway Pest Services for a free estimate and we'll get started right away.

Termite Control

"The Silent Destroyers"

Termites can be a serious, potentially costly threat to buildings and structures. Termites feed on wood which unfortunately can mean they literally eat the very home one lives in.  When it comes to termites, it is often recommended NOT to "Do-it-Yourself." Let Gateway Pest Services identify any infestations and prescribe a cost-effective treatment plan for you.

Bed Bug Control

"Don't Let the Bed Bugs Bite!"

Bedbugs have been around for ages but have more recently made a resurgence particularly in the United States.  Bedbugs are very difficult to kill especially by using pesticides.  At Gateway Pest Control we use  a safe, effective, non-toxic method of treatment using high -heat. This non-invasive procedure will often require only one visit.  Call us today to learn more about our guaranteed treatment.

Heat Treatment and Covid-19

The Coronavirus, also know as Covid-19 is a new viral strain that is  currently being studied by scientists.  There is still much to know about this virus that has caused our recent global pandemic.  What we do know is that it can survive on hard surfaces for  a couple of days at room temperature and can remain in the air for two to three hours. It is known that heat kills viruses (and other pathogens) when exposed to high temperatures over long enough periods of time.  If Covid-19 acts like other viruses, high heat will inactivate it as well. 

Gateway Pest Services uses GreenTech Heat equipment to treat viral contamination in your home, office or workplace. The GreenTech Heat process has successfully been used to decontaminate microbial contamination, including molds, fungi, bacterial, and viral contaminations.

Satisfied Customer Testimonial:

"I’ve got an old house with a dirt cellar and when I moved in I had a severe roach problem. I tried to use natural solutions because I was concerned about my pets. That didn’t work.  Ty came over and assured me that what he uses would not harm my pets as soon as it was dry. After he sprayed one time I didn’t see another roach for over 2 years. I called Ty again when they came back and he sprayed again with the same results. He’s always on time, friendly and professional. I would recommend him and will use his services in the future."
