What do rats eat? Well, they will eat just about any food they encounter during their daily scavenges. While they may prefer nuts, seeds, fruits, and grains, they are omnivorous. This means they will take any opportunity to eat a wide range of foods, including human and pet foods. Opportunities may be crumbs on your floor or counters, or leftovers sitting on the counter.

Rats will enter your home if they think it will lead them to a food source. You may find them in your pantry or see evidence of their presence, like holes in bags or boxes of food. They may even leave a trail of food that leads back to their nest.

There are simple ways to prevent rats from entering your home, starting with understanding and eliminating their food sources. You don’t have to do this alone, however. Critter Control can help you safely and effectively deal with rats in your home.

What Do Rats Like to Eat in the Home?

Rat diets differ from human diets because rats will eat just about anything, even if it is uncooked and still in its packaging. They will chew through bags and boxes to get to cereals, chips, crackers, pasta, sugar, and grains. They will devour crumbs left on counters or floors. Rats even enjoy human trash. What we see as garbage, they see as an opportunity for a meal.

Rats in homes tend to feed on pantry items and dry goods like:

  • cereals
  • grains
  • pet food
  • other stored food

They don’t have any favorite foods. However, some rats, like the Norway rats, are known to particularly enjoy eggs, mac and cheese, and cooked corn kernels.

Knowing how to protect your groceries and cooked foods from rat contamination will help keep your family safe from any diseases rats may carry.

How Do Rats Access Food in the Home?

Rats have many characteristics that make it easy for them to get into your home and access your food sources. For example, rats have some of the strongest teeth among rodents. They can gnaw through plastic, thin wood, and even thin aluminium packaging. In addition, rats have claws on their feet that allow them to climb, jump, and crawl easily on shelves.

Rats can smell and follow scents from the outdoors into your garage, kitchen, storage pantry, or anywhere they can find food. Unfortunately, rats can squeeze through a hole the size of a golf ball, making it even easier for them to get into your home. A hole barely noticeable to humans can serve as an entry point for rodents.

How to Keep Rats Out of Household Food

Although rats are clever when it comes to finding ways into your home, you can outsmart them. There are simple rat removal steps you can take to keep them out of your household food, protect your family from infestation, and not harm the rats. For example,

  • Keep regular cleaning schedules so there are no crumbs or liquid spills to attract a hungry rat. This prevents rats from easily accessing food.
  • Pantry foods with packaging that rats chew through should be stored in rat-resistant containers and sealed. If they can’t sniff or chew the product, you can avoid contamination.
  • Store trash in bins with fitted lids until it is correctly disposed of, reducing scent trails for rats to follow.

Sometimes, you can do everything right to keep rats out of your household food, and you still may find one. It is not your fault. The good news is that with the help of pest control professionals, you can achieve complete prevention and elimination of unwelcome rat populations.

When to Call a Professional

Knowing when to call a professional for help means knowing the signs of a rat infestation. Some signs may be more evident than others. Look for chewed food packaging and trails of spilled food. Rats are known for leaving rat droppings wherever they go, along with urine trails. Rats can enter various areas through small holes. They may even chew holes if a food scent is strong. Finally, you may hear chirping, squeaking, scratching, or chewing noises.

Rather than using DIY methods to trap and eliminate rats in your home, contact a professional. Not only can some DIY methods be ineffective, but you must also know the type of rat you have and match it with the right-sized trap and the most effective bait, which will vary. Placing a trap in the wrong place can increase your rat problems.

Critter Control has a step-by-step process that is highly effective in getting rid of rats for good:

  • Inspection
  • Identifying rat species to create a tailored plan
  • Humane removal
  • Sanitation
  • Long-term exclusion and prevention

We had such a great experience with Critter Control at every interaction. Many months ago, my friend and I called to get some advice on how to handle a bat in our home. The lady we spoke with took the time to give us free, down to earth, real advice. I remembered the experience so when it came time to batproof our attic, they are who we called. The gentleman that came out to do the quote was thorough and patient in explaining everything. The gentlemen that did the bat proofing were quick, efficient and friendly. A few months later we had them back to clean out and insulate our attic. Very friendly crew, extra helpful, and were respectful to our home and good with our German Shepherd. Just a stellar experience all around. Recommended them to my friend, and I'll recommend them to you!

Critter Control was prompt in scheduling the initial visit to assess the problem and detailed in explaining their service. Drew has been prompt in all communications and careful while on the property. It has been reassuring in working with them to resolve the issue.

I couldn’t be happier with my experience with Critter Control and, especially, with Taylor and his partner. Taylor called the evening before my appointment to confirm and took the time to explain what they would be looking for and what the inspection would involve. He also let me know that I would receive a written estimate when they were finished, which I really appreciated. The next morning, Taylor called before arriving and showed up right within the scheduled window. He introduced himself and his partner, and they were both extremely professional and courteous. They took their time inspecting the yard and ultimately determined that I was dealing with both moles and gophers. Taylor walked me through the treatment options, answered every question I had, and made sure I understood what they were recommending. There was absolutely no pressure, and I really appreciated how straightforward and transparent the entire process was. I had a written estimate in hand within about 10 minutes of them completing the inspection. From the initial phone call to the completion of the inspection, everything was handled professionally and exactly as promised. It’s refreshing to deal with people who communicate well, show up when they say they will, and genuinely take the time to answer your questions. Thank you, Taylor, for making the process so easy. I’m very happy with the experience and would definitely recommend Taylor and Critter Control!

I had a appointment with Moises today to investigate noises that I had been hearing in my wall. I explained what I had been hearing and for how long, and he said that he was going to look for any potential entry points. He found two areas that were compromised and showed me pictures of the areas, and told me what he thought was the culprit and also explained the plan to make sure that there weren't any other rodents in the wall by putting in a one way door and then after 5 days, they would sanitize the area in the wall and seal up the two areas, so that nothing else could get inside. He was very professional and friendly and explained everything to me that they were going to do to alleviate the situation. I would definitely recommend Moises and Critter Control for any wildlife removal services in the future.
