Pest Control FAQs, answered by experts

Gnats may eventually go away on their own, but it depends on the source of their attraction. If the environment that’s attracting them—such as overwatered plants, moist areas, or food debris—isn't addressed, they can persist or even increase in numbers. Reducing moisture, improving drainage, and cleaning up organic matter can help eliminate them. Without these changes, gnats are likely to stick around and continue breeding, making it important to remove their breeding grounds to get rid of them for good.

It may be better to have a mouse in your house than a rat. Rats are larger, more aggressive, and more difficult to eradicate once settled. One rat can cause more damage than one mouse. However, both animals pose a danger in that they can spread bacteria and contaminate food, so you’ll want to contact an exterminator as soon as you detect an infestation of either animal.

There are a few main causes of bed bugs. You can pick up bed bugs through traveling since these pests can hide in the seats of buses, taxis, airplanes, and other vehicles as well as seats at restaurants, hotels, and other public places. Bed bugs can also travel on purses, backpacks, luggage, and other bags. Another main cause of bed bugs is multi-unit housing, such as apartment complexes or college dorms.

It’s unlikely true water bugs will get into your home plumbing system. You may find them in gutters, rain barrels, or open irrigation on your property. If there are bugs near your indoor pipes, leaky sinks, or other moist places, they are probably Oriental cockroaches. Consult a pest control professional to determine the pest hiding out in your plumbing system.

When baiting an iguana trap, several items should be avoided. Do not use poisonous baits, such as those intended for rats or mice. This practice is often illegal, is unlikely to attract iguanas, and poses a significant risk to pets or other wildlife. Additionally, avoid using herbs, fruits, and vegetables that are toxic to iguanas, such as fresh sage, rosemary, avocados, and eggplants. While ripe fruit can be an effective bait, be sure to remove any pits or seeds from fruits like apples, pears, and peaches, as they are highly toxic. Finally, steer clear of citrus fruits, which act as a natural deterrent.
