"That there was a follow up done by (Matt) their quality control manager and we were able to come up with some points in seeing a more improved lawn in the future. They even sent out a inspector to do a quality inspection."

"FLEA, TICK & MOSQUITO CONTROL I've had nothing but great experiences with Turning Green. They are exceptionally responsive to phone calls & emails. Their technicians are the nicest, most thorough workers every time they come out to spray. I have 2 large dogs so I worry about ticks & fleas. This is my second season with Turning Green. I've had no issues with ticks, fleas or mosquitoes. Its awesome to be able to enjoy my deck & yard with no worries of pests!"

He explained in detail what he saw,.. looked in all areas inside and outside my home and suggested exactly what I needed.

Pest Control FAQs, answered by experts

DIY animal removal is rarely a good idea and is not advised for many reasons. First, these types of animals can carry diseases and, therefore, pose a health risk to you, your family, and your pets if mishandled. Second, depending on your city or municipality, it may be illegal to remove or handle wildlife yourself. 

Sealing your home against these animals yourself is also a bad idea. Trapping an animal under your house will cause odor and insect problems when it passes away. 

You can easily find sprays that claim they are safe for pets and kids. However, we’d rather not use them in our own homes if we’re worried about pet safety: They still include pesticides and other chemicals, and are best avoided in any food prep areas like the kitchen, or any spots where children and pets may place. That’s why sprays didn’t end up in our suggestions for the safest options.

Spider egg sacs are meant to last, so you can't crush them. One of the best ways to deal with them is to vacuum them up and then quickly dispose of your debris in the trash so the egg sacs leave your property permanently. Egg sacs surrounded by little spiderlings means that it has already hatched, but you may be able to catch many of these with a vacuum cleaner, too.

Spraying for ticks does a good job of eliminating the existing ticks in your yard. Moderate to severe infestations might require several treatment sessions, but most infestations are well controlled with enough treatments, regardless of their severity.

However, wildlife, pets, and people can still carry ticks into a yard, even after treatment, so if you're concerned about ticks in your area, it's a good idea to spray annually for tick prevention.

If there is food sources and other places to build a nest, wasps may come back after their nest is gone. However, if you take measures to repel wasps, like planting pest-repellent plants or sealing cracks and gaps around the outside of your home, they aren’t likely to return. Be diligent at checking for new nests each spring to get rid of them as soon as possible and prevent bigger swarms of wasps in your yard.
