Pest Control FAQs, answered by experts

It is very difficult to remove a colony entirely without using some kind of insecticide. However, some treatments are safer than others. Diatomaceous earth is a non-toxic powder application that creates barriers that insects can’t pass through. Some pest control companies offer liquid nitrogen treatments to freeze out termites without using pesticides. Some chemical treatments are safer to use around plants, water, and wildlife than others. Bait stations are generally less damaging to the environment than sprayed termiticides.

These are the signs of bed bugs to look out for:

  • Blood or rust-colored stains on mattresses, fabrics, or upholstery

  • Dark spots of excrement that look like dots from a fine-tipped permanent marker

  • Tiny eggshells and yellowish shed skins

Through monitoring, preventative treatments, and advising on moisture control.

While you might want to cut corners by either borrowing or purchasing used live traps for catching rats, this can be dangerous because those traps could contain leftover viruses and bacteria that will enter your home. Always start fresh with new materials to avoid contamination.

Fleas thrive during the warmer months, starting in March and running through November. However, the prevalence of these pests depends on the climate in your state. That’s why it’s important to stay vigilant for fleas on your pets and property during spring, summer, and fall. Be sure to apply flea prevention sprays and medications to their coats as directed by a veterinarian.
