Problems with sewer rats are familiar to everyone. They come to the surface, help themselves to scraps lying around and disappear back into the sewers, where they are safe from predators.

In a small study by private organizations, wildlife cameras with SIM cards were hung in many manholes. It turned out that the rats did not eat any baits. What they did, however: They climbed up the steps, up the dirt trap and out through the manhole cover holes. Typically at night, around 0:00 and then wandered back into the channel around 5:00. Thus, it could be concluded – based on the location of the study manholes – that the rats ingested food in the neighboring food service establishments and garbage cans and, as soon as humans became active again (gg 5:30 a.m.), returned to the safe sewer system.

For decades, rat poison in particular has been used in sewers to control the rat population. Rat poison in the sewers, however, contaminates our underworld and the water veins of the sewers. The fact is, the toxins are already in our food chain because fish ingest the toxins. Therefore, it is important to avoid rat poison as much as possible.


Many sensitive areas should be kept as free as possible from harmful rodents. In the videos, Sebastian Junge and Daniel Schröer present our alternative all-round concept for poison-free rodent control in the canal. They show you how you can control rats holistically and sustainably with the targeted use of individual products, and do so entirely without toxins.

In the short video, Sebastian Junge introduces you to the individual products of the concept. In the longer video, he and Daniel Schröer go into more detail about the different areas of application and provide more detailed information.


We have summarized the contents of the videos for you in writing so that you can read all the information again clearly.

What to expect in the Case Study:

  • The concept of holistic rat control
  • Learn how to exclude rat populations at concise points.
  • Presentation of the products that have been developed for years and have proven themselves countless times in use.


Council Cap

Blocks the way of rats in and out of the sewer system

The Rat Cap prevents rats from coming to the surface through the manhole covers. For this purpose, the bracket is simply attached to the dirt trap and closes the gap that the rats can otherwise use.

Installation with the mounting clips is simple and takes place within seconds.

Our Rat Cap® costs little and keeps rats out of the sewer to the surface where they can eat food scraps and retreat. We thus reduce populations biologically and sustainably. The solution can be purchased directly from us by municipalities and cities.


Poison-free monitoring – detect rat activity in the sewer

In order to target the rats, you first need to know where exactly the rats are. The completely toxin-free NARA monitoring blocks are ideal for this purpose. If there are bite marks on the NARAs, you know that there is rat activity at that location.

Our NARA monitors are made of flavored plastic, making them extremely durable and mold-resistant – ideal for use in wet ductwork.

Plague Cam

Digital monitoring around the clock

The PestCam is specially designed for use in permanent pest monitoring. Instead of checking gnawed bait, you can view what the camera is recording from the comfort of your tablet or smartphone. When something moves or the temperature sensor strikes, the camera takes a photo and a video.

The highlight: The PestCam is waterproof and therefore perfectly suited for use in sewers.

Outdoor direct

Digital trap – signals directly to the cell phone

eMitter® Outdoor Direct is the perfect stand-alone solution for digital pest control. You can view the status of the trap at any time – either via the online portal or directly in the eMitter® Pro app. Here you will not only be informed whether the trap is cocked or triggered, but also get a daily sign of life. This way you can be sure that the trap is active.

The trap can be placed directly in the channel and does not require a router or gateway.

Bird of prey perch

The most natural way of pest control

The raptor perch is used for natural and non-toxic rodent control by encouraging birds of prey to settle in the immediate area and providing them with a good vantage point for perching. The perch allows the birds of prey a good vantage point from which they can survey a large area and hunt their prey.
