"I had an infestation of cicada killer wasps. It's taken several attempts by Expert Pest Control and Tony the exterminator who's doing his best to rid my yard of these scary looking wasps. I think this is more difficult as they make their nests in the ground and hard to locate every single one. However Tony has gotten rid of most, and coming back again to try to finish up. He and his company have been very patient."

"Alan came out to look at the site and do some measurements.  Then we communicated several times by email.  He was very good at keeping me informed of his schedule and the likely date he could complete the project.  He came out when he promised, and finished the work in just over two hours.  I was present as he did the work, and I was amazed at the speed at which he completed the task.  He also sent me an invoice by email the same day.  He offered a lower price upon completion because of how he could save on the wood costs.  I paid him the full price we had agreed upon verbally because I felt he deserved the bonus for his commitment to cost control.

Pest Control FAQs, answered by experts

The cost to hire an exterminator or pest control service is $175 on average, with typical costs ranging from $100 to $500. However, you could spend more depending on several factors, including the type of pest, the size and severity of the infestation, and the number of visits required.

Service costs also vary by frequency:

• One-time service: $300–$550

• Initial visit with ongoing service: $150–$300

• Monthly visits: $40–$70

• Quarterly visits: $100–$300

• Annual visits: $300–$550

The type of pest significantly impacts the price. For example, exterminating spiders typically costs between $100 and $300, while a termite problem can range from $230 to $2,500 or more, depending on the extent of the damage. Routine pest control services can help prevent future infestations and costly damage to your home.

Squirrels follow a diurnal routine like humans, remaining quiet at night because they sleep. Homeowners concerned about squirrels in their homes are more likely to hear these critters in the early morning when they awaken, eager to start their day and search for sustenance. As the sun sets, squirrels wrap up their daily endeavors and return to their cozy nests for the night's rest.

Make it easier for your inspector to do a thorough assessment by preparing your home ahead of time. That includes:

  • Noting any signs of pests around the home

  • Removing obstacles in the way of the attic, basement, plumbing, garbage, and other key areas that inspectors will need to access

  • Keeping children and pets away from inspection areas

No, you shouldn’t have to worry about bats in your yard as long as they don’t make their way inside your house. Typically, bats hang around backyards in order to consume bugs, especially if they’re located in the U.S. Bats that are native to North America can consume more than 500 bugs per hour, so they may actually benefit your yard if mosquitoes are prevalent.

Most treatments take 3-8 hours, with follow-up visits recommended within two weeks to ensure complete elimination.
