"The last was a rental company that we have and we used them for an air conditioning and heating system. It was Bototach Mechanical. It’s been a good program for us. They’re very responsive. I don’t know what the thought process was. My husband said, well let’s try these guys and so we did. We have an older home and it’s proved to be a very good deal. The quality has been pretty good, so I would give them an A for the quality. I will give you one helpful hint though. If the company decides they want to replace an appliance, you need to call them and negotiate with them because you can upgrade, but you need to talk to them in person not just do it over the internet."

Pest Control questions, answered by experts

When you spray a roach, the chemicals, usually a mix of neurotoxins like pyrethroids or pyrethrins, start affecting its nervous system almost immediately. It disrupts the roach’s nerve signals, causing paralysis and eventually death. You'll often see the roach twitch, flip over on its back, and stop moving within seconds to minutes.

Stink bugs don't build nests, but they do like to hang around out of sight. They typically hide in cracks, crevices, and tight spaces within buildings, especially during the colder months. They are often found in attics, crawl spaces, and along walls or ceilings. To find them, give these areas a detailed inspection, particularly around windows, doors, and vents.

A rat nest often looks like a messy, loosely formed pile hidden in a quiet spot. It may appear as a ball-shaped cluster or just a scattered heap made from shredded paper, fabric, insulation, leaves, twigs, and other soft materials. Rats gather whatever they can find nearby to build their nests, often tucking them away in walls, attics, or behind appliances for warmth and safety.

Groundhogs usually keep their cool despite being easily spooked. However, there are exceptions—they might get defensive or territorial if they feel threatened or overly concerned. If they sense a threat to their babies, they could get feisty, too. These wild animals are not meant to be kept as pets. If you find babies or an injured groundhog, contact your local animal rescue or wildlife service for guidance.

It can be difficult to know what type of animal is in your attic until you see it. But several clues can help you narrow down the suspects:

  • Sounds: Smaller animals like rats and mice make scurrying and tapping/gnawing sounds. Larger animals like raccoons and opossums make louder clambering noises. Also, note when animals are noisy: Squirrels are active during the day, while rats are busiest at night.

  • Droppings: Rats and mice leave small, rice-shaped droppings (the rat’s version is significantly larger). Bigger droppings belong to larger critters like raccoons. As long as you’re not squeamish, an image search can help you identify what you’re seeing in your attic.

When in doubt, take photos of damage or other evidence and show them to an experienced pest control pro.
