Today's Homeowner looks at dozens of datapoints on pest control companies to come up with our data-driven rankings. It's not possible for a company to pay for preferential treatment in our rankings. We look at the following key factors in determining who should top our list:
Today's Homeowner has narrowed down the top pest control experts so you can find the right provider for you. We analyzed pest control treatments offered, costs, customer reviews, state availability, contracts, and more.
This is how the top pest control companies ranked in Alton:
Terminix has several hundred branches in over 22 countries and has been in the pest control industry for almost 100 years. The company offers effective pest control treatments that are safe for you and your family.
Terminix exterminates all types of pest issues for residential and commercial customers. These include rodents, ants, spiders, raccoons, opossums, roaches, and termites. Terminix’s typical pest regimen includes a home inspection and preliminary treatment, followed by three additional treatments over the course of a year.
Orkin has been around for over 100 years. Its exterminators need to complete 160 hours of training. And, due to its big network, it can usually provide next-day — or even same-day — visits.
Orkin’s most popular pest control plan is its annual pest control contract. Orkin’s typical pest control plan is also seasonal, meaning your home will be treated several times during the year.
Rentokil is a respected name in pest control, with providers across the globe and almost a century of experience in the industry. In North America, Rentokil is the parent company of several local pest control providers like Western Exterminator, J.C. Ehrlich, and Presto-X.
Rentokil provides integrated pest management (IPM) services, which means your pest control specialist will focus on both eliminating existing pests and preventing future infestations. Rentokil’s services consist of preventative maintenance, treatment, and monitoring for pest infestations.
Not all pest control services are the equal in reputation, qualifications, and proficiency. Evaluating companies helps you identify the right choice for your pest circumstance. Focus on these key factors when choosing a pest control company:
Look for a pest control company that is able to handle the type of pest you have, whether it’s termites, bed bugs, roaches, rodents, or something else. The company should be able to describe how they treat your type of pest.
When choosing a pest control company, look for technicians that hold certifications from respected industry associations, like the National Pest Management Association (NPMA), on top of proper state licensing. Solid credentials indicate that the technicians have completed adequate training. Also ask about required training hours and continuing education.
Before scheduling an appointment, spend time reading online reviews on sites such as Google or Yelp to see which providers have a reputation for providing positive experiences and effective services. Also look for complaints with the Better Business Bureau. Inquire about ongoing training at the company as well as how its technicians stay up to date on the latest pest control methods and treatments. When you select a professional from our list of the top pest control in Alton, you can feel confident knowing that you're hiring an expert that meets our quality and review standards.
Search for companies with “green” certifications if you want more natural, eco-friendly pest control. You can also ask about humane trapping programs that don't harm pests like mice or snakes. Keep in mind that stronger treatments might be a better option for major infestations. Whether you choose eco-friendly or traditional options, any pesticides (besides those classified as minimal risk) are required to be registered with the EPA.
Leading pest control professionals typically offer service guarantees for ongoing plans. This means that if pests remain after the initial treatment, the company will make another visit and re-treat your home at no cost until the infestation is taken care of. One-time treatments might not have reservice guarantees.
Once you have narrowed down your top pest management companies, contact each one to ask questions such as:
Analyze potential pest control companies based on their answers to these questions. This will enable you to select the right provider to effectively solve your pest problem at a reasonable cost.
A variety of pests like to find their way into Alton homes. Some are relatively harmless, but others can damage your home and carry diseases. All of them can give homeowners anxiety. Our team studied around 10 million social media conversations to determine the pests that are the biggest headache in the area.
Our top picks for pest control companies are Terminix and Orkin. They're respected in the industry and help get rid of all common pests.
Hiring a pest control company and getting a professional to spray your property regularly is the best way to prevent future pest infestations. This deters insects and animals from coming inside your home.
To find the best pest control company for you, the key is to take your time and research your options thoroughly. We recommend obtaining quotes from several companies and reading reviews to help figure out which company is the best for you.
Pest control involves exterminating unwanted insects like bees, fleas, and other unwanted bugs or wildlife from your home. When you hire a pest control company, a professional exterminator will come and inspect your property. Then they will use various techniques to remove the pests and stop them from returning, such as chemical or natural sprays, bait, and traps.
Many Alton homeowners wonder about the cost of pest control. Monthly pest control usually costs $40 to $70 per visit. Quarterly pest control costs about $110 to $250 a visit. To find out exactly how much it will cost for you, we recommend contacting several providers for a quote.
If you already have a serious pest infestation, you should seek pest control as soon as possible. However, if you just want preventative pest control, the best time of year to have a professional spray your home is in the spring before colony numbers get too high when it's warmer. But it’s never too late for pest control. You can still spray in the summer or any other season and see effective results.
