Pest Control questions, answered by experts

High-frequency bird repellent devices are effective at driving away birds, which is their intended purpose. However, these devices also tend to have unintended negative consequences. For example, if you or your neighbors own pets, the high-pitched noise emitted by these electronic devices will cause them distress and may even make them aggressive.

For a minor infestation, you can expect to clear up a German cockroach problem in about two weeks. That’s usually enough time to confirm that they don’t have additional hiding spots and aren’t continuing to encroach from an outside source. If you have a major infestation and use the services of a pest control company, it can take several weeks and multiple visits to fully clear your home, up to a couple of months.

You can 100% get rid of roaches, but it takes weeks or months of consistent killing effort, meticulous kitchen clean-up, and airtight food storage. Working with a local roach control pro to fight an infestation enhances your DIY efforts to ensure total elimination. A multi-pronged approach with a roach contractor prevents repeat infestations.

Yes, it’s safe to sleep in a house with termites. They don’t bite or spread disease and they aren’t likely to crawl on you or invade your personal space. However, termites can cause serious structural damage over time, which may compromise your home’s safety if left untreated. If you suspect an infestation, it’s best to schedule a professional inspection and treatment to prevent long-term risks to your property (not to mention your peace of mind).

No, the spotted lanternfly does not sting, bite, or otherwise do anything painful or damaging to humans or animals. Do not hesitate to approach and kill the insects and any eggs you find on sight—you’ll be playing an important role in slowing the spread of these invasive and destructive pests. If you’re not sure if the insect is a spotted lanternfly, snap a picture and contact your local extension office for help identifying it.
