Pest Control questions, answered by experts

For routine pest control maintenance, most specialists recommend treatments every three months (quarterly). However, the ideal frequency can range from monthly to yearly depending on several factors. If you have a severe infestation, more frequent treatments will likely be necessary. Your location also plays a role; for example, homes near water may experience more pests in spring and summer. It's best to discuss your specific situation with a pest control professional to determine a suitable schedule. If you notice any pests between scheduled visits, inform your provider so they can address the issue promptly.

When you spray a roach, the chemicals, usually a mix of neurotoxins like pyrethroids or pyrethrins, start affecting its nervous system almost immediately. It disrupts the roach’s nerve signals, causing paralysis and eventually death. You'll often see the roach twitch, flip over on its back, and stop moving within seconds to minutes.

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.

Carpenter ants can go away on their own if their food source is eliminated, but this could take weeks or months. If you have an infestation on your hands, carpenter ants need to be treated by pesticides from a licensed professional in order to go away as soon as possible.

According to the Internet Center for Wildlife Damage Management, no frightening devices are proven effective for squirrel control. This is likely because the squirrels quickly become habituated to the noises. However, strobe lights show some promise, so motion-activated lighting could be an option worth considering as part of your integrated pest management strategy.
