Pest Control FAQs, answered by experts

Leaving lights on is not an effective or foolproof method for keeping cockroaches away. While roaches are nocturnal and prefer darkness, light alone is not enough to stop them, especially if they are seeking food, water, or shelter. A bright light might temporarily discourage them, but hungry or determined roaches will often adapt and venture into lit areas. For more effective cockroach control, it is better to focus on proven prevention methods. These include maintaining cleanliness by eliminating food crumbs, sealing cracks and entry points, reducing clutter that provides hiding spots, and fixing any moisture issues. Using traps or repellents can also be part of a comprehensive strategy.

Carpet beetles do not bite humans, but their larvae can cause skin irritation that’s often mistaken for bites. These tiny, bristly larvae have barbed hairs that can lead to allergic reactions in sensitive individuals, resulting in red, itchy welts or rashes. While the irritation may resemble bug bites, it’s actually a response to contact with the hairs or shed skins, not an actual bite. Adult carpet beetles are harmless and primarily feed on pollen, but their larvae can damage natural fibers like wool, fur, or leather in carpets, clothing, and upholstery.

Spiders are not typically attracted to bedding as a primary source of food or shelter, but they sometimes inadvertently end up there. Spiders can hitch a ride on your clothing, belongings, or through open windows and doors. The underside of a bed, especially if it's near a wall or corner, can provide such a sheltered spot where they can hide and build webs. Dust and clutter under your bed can create ideal hiding places as well. If your room has other insects like flies or mosquitoes, spiders may be drawn to the area in search of prey. 

Rat poison that contains an anticoagulant like warfarin can cause bleeding, chills, confusion, extreme fatigue, headache, convulsions, lightheadedness, and seizures. Anticoagulants prevent your blood from forming clots, which can result in uncontrolled bleeding both internally and externally. Other types of rat poison that aren't anticoagulants attack your liver, kidneys, and digestive system. They can suppress your breathing and heart rate, causing low blood oxygen and poor circulation. Burning in your throat and gastric discomfort are common symptoms.

Finding one termite could be a sign of an infestation. This termite could be a worker looking for food or a swarmer responsible for reproduction. Any time you see a termite crawling or flying around your home, or if you see their discarded wings around doors and windows, it’s time to call in a pro for an inspection.
