Pest Control FAQs, answered by experts

There is often confusion between fleas versus ticks, bedbugs, carpet beetles, lice, fungus gnats, and flea beetles. Learning how to identify and differentiate between these insects is key for effective treatment. If you are unsure, it's always best to consult with a pest control professional who can properly identify the pest and provide the best treatment options.

Ask your friends and family for recommendations for exterminators. You can also browse online for reputable ant control companies in your area—make sure they have glowing reviews and the proper licenses and permits. 

Give them a call, and they can take a look at your infestation, determine the type of ant they’re dealing with, and give you a cost estimate. Then, you can compare quotes and choose the pro that’s right for you.

Roof rats are relatively small rodents that typically measure around six to eight inches in length (excluding their long, scaly tails that are often longer than their bodies). They have sleek black or brown fur, pointed snouts, and large ears. In general, they are typically smaller and darker in color than common brown rats.

While water bugs are considered generally harmless to humans, they can bite humans if threatened. Cockroaches are often incorrectly mistaken for water bugs. In this case, cockroaches can bite but are unlikely to bite humans. 

Water bug bites can be very painful and cause symptoms such as redness, swelling, and allergic reaction. Bites will usually heal on their own. However, if you experience severe symptoms or an allergic reaction, seek medical help immediately.

Roof rats can carry a variety of pathogens and parasites, including salmonellosis (food contamination), leptospirosis, trichinosis, rat-bite fever, murine typhus, plague, and toxoplasmosis. Diseases can be spread via urine, droppings, or saliva. To prevent transmission, it’s essential to promptly address a roof rat infestation and avoid direct contact with the animals where possible.
