We’re the only company in the industry that reacts to mosquito behavior. Without a set schedule, we can adapt to your yard's needs and the mosquitoes around it.
On average, we visit every 10-17 days to ensure a mosquito-free lifestyle.
Our special blend began 20 years ago and we continually evolve it to maximize effectiveness.
Science created our formula, and science continues to adapt it so it remains the most effective spray in the game.
All of our technicians are trained in environmentally smart practices. They target active mosquito areas and are taught the signs to recognize them.
This means less overall spraying, more dead mosquitoes, and a healthy ecosystem in your backyard.
If you’re not happy with our services, let us know. We’ll work hard to make it right, including offering a service call spray if needed.
If you’re unhappy with the results after your first visit, simply notify us within 7 days and we will issue you a full refund.
Welcome to Mosquito Shield of West St. Louis. Mosquito Shield is setting the industry standard for mosquito and tick control by utilizing a proprietary blend of natural plant oils, select control products and a flexible spraying schedule that maximizes effectiveness.
The company was founded in Massachusetts in 2001 in direct response to the absence of an effective and affordable mosquito barrier spray. The company developed a patent pending barrier spray that once started, lasts for weeks and grows in strength as the season progresses.
Owners Arthur & Michele Harmon moved their family to St. Louis in 2008. Through the years, Arthur has worked in various business settings including car and truck rental, information technology, manufacturing and home services. He has created a great reputation for exceptional service and integrity with the work he has done while balancing his work and family life. Michele’s experience is in operations in a large corporate setting; driving performance focused on customer excellence and service delivery, which translates excellently to the mosquito and tick control service business in West St. Louis, MO. She has traveled globally to work to integrate new acquisitions as well as to solidify brand integrity and customer experience across several brands.
Outside of work, the Harmons enjoy exploring the State and County Parks in Missouri including favorites such as the trailheads along The Katy Trail and Castlewood State Park.
Michele says, “As someone that has always had an extreme reaction to mosquito bites, as well as a daughter who must have an epi-pen available if she gets bitten, we were often times forced to limit our time outside.”
Our goal is to provide the best mosquito and Tick control with the highest levels of customer service, allowing our customers to enjoy their yards, homes and time with family and pets to the fullest.
We use an insecticide so other insects present when and where we spray may be impacted.
However, our formula was specifically engineered for mosquitoes so it won’t repel any other insects as it does mosquitoes.
Every yard is different but you should notice a dramatic reduction within 24-48 hours of the initial spray.
With each subsequent treatment, the results continue to improve, allowing you to enjoy time outside without being chased in by swarms of mosquitoes.
