Rat Prevention FAQ
Rats are an unpleasant nuisance in all urban areas. Below are frequently asked questions about rats in our community.

1. If I see a rat, what should I do?
If you spot a rat inside or outside your home, please report it to the West Allis Health Department. Please provide your name, phone number, address, and the address of the sighting if the rat was spotted outside of your home. 

2. What will the Health Department do if I report a rat? 
The West Allis Health Department will provide tips and educational information on preventing rats in and around your home, and recommend the strategies you can implement to deter rats. The Health Department cannot provide extermination services, but can use enforcement and issue orders to properties that are contributing to the problem. Property owners may seek extermination services at their own expense. 

3. Are rat sightings on the rise?
Reported rat sightings have been on the rise in recent years, due to several variables. The warmer, milder weather throughout the seasons has given rats more efficient living conditions, which support breeding. There has also been more awareness of the rodent problem, leading to more reports. 

4. Do vacant properties attract rats? 
Habited, maintained properties tend to attract rats because these properties provide resources like food, water, and shelter. Well-kept homes with gardens, bird-baths, ground cover, and other outdoor amenities can attract unwanted rodents in addition to other animals. 

5. Do rats live in sewers?
No, however they will congregate and travel in the sewer system. Rats live above ground in burrows, and build their burrows in areas they deem safe and food-secure. Rats prefer to burrow in soft dirt, many times next to or along a foundation of a garage, or under a shed, deck or covered porch. Residents are encouraged to take necessary steps in preventing rats, such as keeping their yards clean and free of debris.

The City does not trap rats, and baiting is only done in the winter months in sewers in highly impacted areas. The most effective rat abatement solutions tend to be action taken from residents themselves.

7. I heard I can’t have bird feeders or birdbaths. That’s not fair!
Bird feeders and bird baths are welcome in the City of West Allis, but can attract rats. Bird baths offer rats a source of drinking water, and rats will climb up to bird feeders to feed from them, or can be attracted by spilled seed on the ground. If you choose to feed or water birds, City ordinance requires cleaning spilled birdseed from the ground each day.  Residents are also encouraged to empty bird baths and bring bird feeders in at night, when rats are most active. If rats are spotted in your area, stop feeding birds.

8. We had a rat sighting in our yard, and I’d like to put out rat poison. Can I do this?
There are no City ordinances forbidding the use of pesticides in private yards. However, residents must take caution, as stray animals, pets, and unsupervised children may come in contact with the poison. The first step in rat abatement should always be identifying what attracted rats to the area in the first place, and eliminating these sources of food, water, or shelter. Rats will continue to infest areas that offer them secure living conditions. When using pesticides/rodenticides, always read the manufacturer's labels and follow the directions for placement and usage.
