"I am employed by a property management company. When tenants bring in unwanted pest, it's imperative we get rid of them quickly. Rob, our Pestquito Tech and Lindsey our account manager make it their mission to kill! We had a larger more reputable company before, but they couldn't get the job done. Rob and Lindsey get it done! They are very careful to keep the roaches from spreading to other units. They also take care of other pest and they aren't afraid to get dirty. The tenants are grateful and so am I. I highly recommend Pesquito. Thank you Pestquito. Job well done!"

Pest Control FAQs, answered by experts

Mice, rats, and other rodents are survivalists. They've developed a set of skills that can help them survive even in challenging, predatory conditions. For that reason, they can be hard to get rid of once they've staked their claim in your home. Often, the best way to get rid of rodents is to keep them from getting into your home in the first place.

Scorpions are repelled by strong scents like lavender, cedar, peppermint, and cinnamon. Applying essential oils of these scents mixed with water around your home's perimeter and entry points can act as a mild, chemical-free deterrent. In addition to scents, scorpions also tend to avoid well-lit areas, preferring to hide in dark, cool, and damp places during the day. However, it's important to note that these methods are not fully effective on their own and should be combined with other preventative efforts, such as sealing any potential entryways into your home.

Although it takes time and possibly multiple treatments, roaches can be eradicated from your home. However, they can return if the conditions are right. That’s why taking the steps to prevent an infestation is key. You may also want to discuss preventative pest control treatments with your exterminator. That way, you can reduce the risk of another infestation. 

Like a rent-controlled apartment in New York City, rodents know a good thing when they see it. If they've found a cozy nest inside your home, they will set up camp and stay there, leaving only to forage for food and water. As long as they have a warm place to sleep, raise their young, and continue access to water and food, they're going to stick around.

It is very difficult to remove a colony entirely without using some kind of insecticide. However, some treatments are safer than others. Diatomaceous earth is a non-toxic powder application that creates barriers that insects can’t pass through. Some pest control companies offer liquid nitrogen treatments to freeze out termites without using pesticides. Some chemical treatments are safer to use around plants, water, and wildlife than others. Bait stations are generally less damaging to the environment than sprayed termiticides.
