This morning, I went out into the garden—just to water the flowers and check if the cats had yet relieved themselves, as they often do. But as soon as I opened the gate, a horrible smell hit me. So strong that my chest tightened and I felt a metallic taste in my mouth.

 Secure the Area & Protect Yourself

Step Back Immediately: Move away from the area and go back inside if you are still outside.

Close Windows & Doors: If the smell is strong enough, it could be a gaseous or airborne substance. Prevent it from entering your home.

Wash Thoroughly: If you think you may have been exposed, wash any skin that was uncovered and rinse your mouth with water. Remove your shoes and clothes near the door and wash them separately.

2. Call for Professional Help (This is Urgent)

This is not a situation for a regular pest control service. You need emergency responders who are trained for hazardous materials.

Call the Non-Emergency Fire Department Line or 911. Describe exactly what you told us:

A strange, moving, slimy substance with a horrific rotting smell.

Your physical symptoms (chest tightness, metallic taste).

That you fear it could be a hazardous material or chemical.
