  The damage caused by rats can look like the work of other insects and pests, so you may find it difficult to determine which type of infestation you’re dealing with. In general, rats nibble at anything in their way, much more than mice do. They also leave tracks forming two parallel and slightly notched lines with a space of about 4 millimeters between them.

Although the main character of the animated movie Ratatouille was a gentle soul who loved tasty stews and become top chef at a fancy Parisian restaurant, the sewer rats that invite themselves into your home have nothing to do with cartoon cuddliness. The real thing has long been associated with plague epidemics for good reason; rats are carriers of disease and their presence puts humans’ health at risk.

• • Toxoplasmosis is a disease that affects the fetuses of pregnant women and is especially dangerous for immunocompromised persons.
  • Leptospirosis is contracted through rat urine and causes diarrhea and vomiting.
  • Streptobacillosis causes fever after a rat bite; it is less common in modern times.
  • Murine typhus and allergies are caused by rat fleas, ticks and mites.

Rat infestations usually come via the sewers and pipes. That’s where our rat exterminators will begin their search during an inspection of your home or commercial building. As they search for clues, they may use surveillance cameras to determine the extent of the infestation and the location of the rat burrows.

If you are dealing with a small number of rats, the installation of traps and baits may be sufficient, but if it is a well-established colony, use of various types of poisons will be required.

Our extermination strategies always aim to prevent rats from dying indoors; after all, nobody wants to smell a dead rat inside their home. We may use a special type of poison that merely makes the animals feel ill so they leave the premises voluntarily.

After our exterminators have removed the rats, we track down and block off the places where they may have entered. We often work in collaboration with a plumber who performs smoke tests to check the condition of the piping. It’s very important to carry out this work without delay to avoid a re-infestation.

Our rat exterminators also offer a home sealing service to block holes and seal off any tiny or large openings through which rats or other rodents can pass. We install wire mesh on rainwater drain pipes and ventilation vents, and we block any cracks and gaps with cement or other sealants.
