Southern Delaware 
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.
At Mosquito Shield of Southern DE, our goal is to provide the best mosquito control with the highest levels of customer service, allowing our customers to enjoy your homes and time with family to the fullest.
Owners Brad & Kristi Sutliffe moved to Lewes, DE in 2017 after living on the Eastern Shore of Maryland. Having visited Lewes many times on family vacations we fell in love with the charm and relaxed feeling of living in a small close knit beach town. They often joke that they should have made the move sooner and wonder how they ever lived away from the beach.
Brad grew up in New England, ultimately moving to the Eastern Shore when he was in High School and where he would meet Kristi. He has been in the insurance industry for close to 20 years. Brad is constantly looking at ways to challenge himself and grow. Kristi grew up on the Eastern Shore of Maryland with a background in marketing and feels fortunate to have been able to stay at home with their 3 children, Nate, Emme and William for the past several years.
Brad & Kristi are total foodies, and the Southern Delaware community is not lacking on amazing locally owned restaurants. To name a few, Heirloom, Agave, Blue Hen, Patty’s, Stingray, you can’t go wrong with one of the 18 Sodel restaurants. They also love visiting Cape Henlopen State Park, which is their happy place! From drive-on surf fishing, walking their favorite trail on Gordon’s Pond, fishing on the fishing pier and frisbee golf there truly is something there for everyone. The best part, they continue to unearth new places at the State Park.
During the summer months, you will find our family boating on the waterways of the Delaware Bay and Indian River. One of the most exciting things we’ve joined as a family has been Freedom Boat Club. During the early spring of 2020 before the pandemic hit we joined and haven’t looked back. We were able to use this outlet during the pandemic to feel a sense of normalcy.
Brad’s experience in the insurance world translates very well to Mosquito Shield. He understands the importance of delivering strong customer service in building a book of business. At the end of the day, in small communities your service is what stands out. When asked what attracted them to Mosquito Shield, “The initial appeal for our family is being able to help others take back their outdoor spaces. The countless times we’ve gone to a playground or dined outside and said, the mosquitos are eating us alive, no matter how much bug spray. Mosquito Shield of Southern Delaware will have an April through October operating window which is extremely appealing as we are looking long term. The team that makes up Mosquito Shield is incredible, the question for us quickly became, why wouldn’t we want to work with these people?”

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.
