"Great Service We recently had this pest control company spray our house to help prevent ants, and we couldn’t be happier with the service! We’ve had a pretty bad ant problem during the spring and summer in the past, but they were quick to respond, knowledgeable, and did a great job treating our home. We highly recommend them to anyone looking for reliable and effective pest control!"

Pest Control FAQs, answered by experts

To determine if you have a rat or mouse infestation, look for several key differences. The most obvious is the size of the rodent: rats are significantly larger with thicker bodies, while mice are much smaller and more slender. You can also identify them by their droppings; rat droppings are larger and rounder, about the size of a raisin, while mouse droppings are smaller, like a grain of rice, and often have pointed ends. Other signs include the sounds they make, as rats produce louder scratching and gnawing noises due to their size. Behaviorally, rats tend to be more cautious, whereas mice are more curious and might be seen more often. Additionally, rat nests are typically larger than those of mice. If you are unable to see the pest or find clear evidence, a professional inspection can provide a definitive identification.

Unlike for rats and mice, poisonous baits and fumigants aren’t a legal option for dealing with squirrel invasions. So, don’t set any traps up using standard rodenticides. Remember that you typically need a permit for trapping and relocating squirrels found on your property. Some states even specify the types of traps you need to use.

Fruit flies are more common during warm-weather months and may go away on their own in late fall once temperatures drop. However, they can survive year-round indoors as long as there's food available, so you'll likely want to take a proactive approach to get rid of them and stop the spread of bacteria.

Getting roaches to completely go away will take a lot of effort, and they hardly ever go away on their own. You will likely need a combination of home treatments, like roach sprays and traps, and regular visits from an exterminator, to control an infestation. It can take awhile for these treatments to start working, and you’ll need to stay on top of replacing old traps and having additional extermination services, plus keeping your home clean and decluttered, to deter roaches.

A raccoon may be hanging around your house for convenient access to food, water, or shelter. They may drink water out of puddles, pools, ponds, fountains, or your pet’s water bowls. Raccoons are also known to eat just about anything, including food from gardens and waste from unsecured trash cans.
