Experts are warning households to keep their windows and doors tightly shut for the next several weeks, as sightings of one of the most dangerous spiders in the country are on the rise.

What’s Happening?

As the weather shifts, spiders begin moving indoors in search of warmth and shelter. This particular species, often confused with harmless house spiders, carries a venomous bite that can cause severe swelling, pain, fever, and in rare cases, serious medical complications.

Why the Urgency?

Specialists say that this is the peak breeding season, which means the chances of encountering them in homes is significantly higher. They are drawn to warm, dark spaces—garages, basements, and yes, open windows at night.

What You Should Do:

• Keep windows and doors closed as much as possible.
• Seal gaps and cracks around the home to prevent entry.
• Shake out clothing, shoes, and blankets that have been left on the floor.
• Call pest control if you notice multiple sightings indoors.

The Bite Risk

Most bites happen accidentally—when someone rolls over a spider in bed, slips on shoes it has crawled into, or brushes against one hidden in clothing. While fatalities are extremely rare, the effects of a bite can still be dangerous, especially for children or those with allergies.

Final Word

Experts say these precautions should be followed for at least four weeks, until the breeding season begins to taper off. Taking simple steps now could prevent an unwanted—and painful—encounter.
