You cannot solve a rat problem you cannot locate. Nests are where rats sleep, breed and return to — find it, and you find the heart of the problem. Here is how to track one down.
Step 1: Read the droppings
Droppings cluster more densely near the nest. Note where you find the most — that is your direction of travel. Wear gloves whenever you handle them.
Step 2: Follow the rub marks
Rats travel the same routes and leave greasy, dark smudges along walls, skirting and pipe runs. These "rub marks" are a literal trail toward home.
Step 3: Think warm, dark, undisturbed
Nests are almost always somewhere that is warm, hidden and rarely disturbed, and close to food and water. Prime candidates:
- Behind or under the fridge, oven or washing machine
- Inside sofa or armchair bases
- Lofts, storerooms and cluttered cupboards
- Wall and ceiling voids, especially near pipes

Step 4: Look for the nest itself
A nest is a ball or pile of shredded soft material — paper, cloth, insulation, cardboard — usually with droppings around it and a musky smell.
Step 5: Clear it and keep them from returning
Remove the nest and droppings safely (gloves, mask, disinfectant), then seal nearby gaps and remove food and water. Finally, make the area actively unwelcoming so they do not rebuild. The EchoRepel Ultrasonic Rat Repellent keeps the spot uncomfortable for rats, so clearing the nest becomes a permanent fix rather than a temporary one.
