"Victor was punctual, showed up on the day as promised, removed old fence materials, installed steel posts. Next day brought all new materials and by the fourth day all installed and left the place clean. i was impressed with the service. My wife who was concerned at first with the old fence removed but then she was happy to see the new fence in place in short time. Victor is true professional and reliable handyman/contractor. Victor also helped fixing my leaking shower valve soon after the fence installation."

"Christian from McLay Services showed up within the agreed time frame to install a new kitchen faucet and fix a leak in one of my bathtubs. He did a great job. Faucet was installed within 20 to 25 minutes. He also fixed a leak in my bathtub in the Master bathroom and installed new a new drain and spout. He was neat and clean in his work and answered any questions that I had. Very good plumber. I would recommend McLay Services to anyone!!"

Nest Installation questions, answered by experts

Having a few spiders in your home is okay and in many cases can be beneficial. Spiders can help reduce the presence of other pests, such as flying gnats and mosquitos. If you fear that you have a venomous spider living in your house or a large infestation, you should hire a spider exterminator to help you remove it.

A rodent infestation often has a distinctive, unpleasant smell. The most common odor is a strong, musky scent, similar to stale ammonia, which comes from mouse urine. As the infestation grows, the smell can become more intense. You might also notice a foul, decomposing odor if mice or rats die inside the walls or hidden areas. This combination of smells is a clear sign of a rodent problem and should prompt immediate action to address the infestation.

Ensures thorough identification and eradication, preventing extensive property damage.

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.

Ant and termite infestations look very different. Since termites feed on wood, one of the warning signs of their presence is drooping drywall, peeling paint, loose floor tiles, and crumbling wood. On the other hand, ants feed on plant- and animal-based food options, so you’ll likely spot a colony near your home’s food sources. If you’re unsure what type of pest infestation you have, hire a pest control specialist to inspect for you.
