Pest Control FAQs, answered by experts

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.

Some plants that are toxic to animals or insects are also toxic to people. Daffodils, for example, are considered poisonous to humans (although they are rarely fatal). Most of the other plants listed above, however, are safe (and delicious!) for humans to eat, including basil, rosemary, and lemongrass.

You should never block both the top and bottom of your chimney. Proper airflow is essential because the temperature inside the chimney will still fluctuate as your house warms and cools. Moisture can build up without ventilation, leading to dampness in your walls over time. Blocking the top prevents debris and animals from entering, but the chimney still needs air circulation to avoid condensation issues. Allowing the chimney to breathe maintains the health of your home and prevents long-term damage.

Yes, it’s actually common to see more cockroaches after you spray. It might seem like things are getting worse, but that’s usually a sign the treatment is working. Roach sprays and baits can flush them out of their hiding spots as they try to escape the chemicals. You might notice them acting strangely—slower, twitching, or out during the day when they’re usually hiding.

Stink bugs can start reproducing a couple of weeks after they leave the nymph stages, which gives them several months to mate and start laying eggs. A single stink bug can lay up to 400 eggs in a lifetime, which can worsen an infestation. Stink bugs lay significantly more eggs in warmer climates where they stay active longer and have several rounds of egg laying.
