Pest Control FAQs, answered by experts

You don’t need heavy-duty chemicals to get rid of a bobcat. In fact, one of the most simple and effective methods of preventing bobcats from entering your property is by keeping your yard clear of overgrowth by trimming bushes and trees regularly. This eliminates potential hiding spots for a bobcat and makes them easier to spot in general.

While we can’t guarantee that the removal methods described above will work overnight, they will help eradicate the infestation as quickly as possible. For the most immediate results, consider hiring a flea exterminator that can use high-grade products and removal equipment to wipe out small and large groups of fleas.

Earwigs may look scary with their pincers, but they don’t pose a serious threat to humans or pets. They are not poisonous, do not sting, and rarely bite or pinch unless handled. While they are not known to transmit diseases, their presence can signal underlying moisture problems in your home, such as mold, water damage, or rotting wood. A large infestation can become a nuisance, and certain species may emit an unpleasant odor. Therefore, while earwigs themselves aren’t dangerous, a large number of them may indicate bigger issues that should be addressed by a pest control professional.

Termites are most active and cause the most damage in the spring and summer, when warm temperatures and increased moisture accelerate their activity. This is also when swarming typically occurs, allowing colonies to expand. However, termites remain active year-round, especially in warmer climates or heated homes. An established colony can continue to damage wood 365 days a year, even during cold weather.

To determine if you have a rat or mouse infestation, look for several key differences. The most obvious is the size of the rodent: rats are significantly larger with thicker bodies, while mice are much smaller and more slender. You can also identify them by their droppings; rat droppings are larger and rounder, about the size of a raisin, while mouse droppings are smaller, like a grain of rice, and often have pointed ends. Other signs include the sounds they make, as rats produce louder scratching and gnawing noises due to their size. Behaviorally, rats tend to be more cautious, whereas mice are more curious and might be seen more often. Additionally, rat nests are typically larger than those of mice. If you are unable to see the pest or find clear evidence, a professional inspection can provide a definitive identification.
