"Job went well start to finish. Custom sheet metal and gas pipe retrofitting required for installation was exceptional. Installers were courteous and professional. Overall A+ experience. Prompt and efficient dealing from 1st call to completion. Highly recommended."

"I had him come in for a quote before Christmas but we weren't ready until March. He said to pick out colors at Sherwin Williams where he gets a deal. They had a great color selection. He did the family room, living room and hall all in 3 days. They even moved the furniture and cleaned behind it.

"I have to admit, I was really disappointed with my overall experience. I was told that I could one time do a reimbursement. First off, why would you do that if you have already paid for service?!?! Then it took almost a week to get some one to address my situation. Now, I do realize that it does take time to get things rolling, but a week?? The gentleman that came to do the work was knowledgeable, but he didn't want to work with he Google representative to make sure that my NEST was/wasn't working properly. He was very short with the rep. and after several minutes of debating with him finally gave in and addressed both of our concerns. The other concern I had was, I was told that I would not have to pay anything this time, because of the delay, yet the rep. said I owed $65.00. He showed me the data he had and sure enough it said that I owed $65.00. Why, would a rep. from your own company tell me this and then turn around and not honor it?!?!? I sure hope that it doesn't take that long to get service the next time, that I need to have something done. What ever happened to customer service?? REALLY DISSSAPPOINTED!!!"

Nest Installation FAQs, answered by experts

No, the spotted lanternfly does not sting, bite, or otherwise do anything painful or damaging to humans or animals. Do not hesitate to approach and kill the insects and any eggs you find on sight—you’ll be playing an important role in slowing the spread of these invasive and destructive pests. If you’re not sure if the insect is a spotted lanternfly, snap a picture and contact your local extension office for help identifying it.

Some people find that treating their yards with natural substances can help to repel ticks. In fact, pest extermination companies often offer all-natural lawn treatments to repel ticks. Household ingredients like oregano oil, clove oil, thyme, and citronella ward off ticks and are natural ways to get rid of fleas.

There are a few main causes of bed bugs. You can pick up bed bugs through traveling since these pests can hide in the seats of buses, taxis, airplanes, and other vehicles as well as seats at restaurants, hotels, and other public places. Bed bugs can also travel on purses, backpacks, luggage, and other bags. Another main cause of bed bugs is multi-unit housing, such as apartment complexes or college dorms.

The time it takes for termites to damage a house varies, but it generally does not happen within days or weeks. Significant structural damage typically takes several months or years to occur, with serious damage often taking 3 to 8 years. The rate of destruction depends on factors like the termite colony's size and maturity, the type of wood they are feeding on, and local conditions. It can take 3 to 5 years for damage to become visible and 5 to 6 years for the home's structural integrity to be compromised. However, some species, such as Subterranean termites, are more destructive and can cause extensive damage in as little as 2 years. Because of this risk, it is important to treat your home as soon as you notice any signs of termites.

It is highly unlikely that fleas will go away on their own without treatment. Female fleas can lay dozens of eggs per day—up to 50—causing their numbers to multiply quickly and spread throughout your home. An adult flea can live for around 100 days or even up to a year as long as it has access to a host, such as a pet or human. Even without a host to feed on, fleas can survive for weeks. Because of their rapid reproduction and resilience, it's best to tackle a flea problem as soon as possible. Hiring an exterminator is recommended to prevent the infestation from worsening.
