Rats are more than just a nuisance — they can chew through wiring, contaminate food, and carry serious diseases. If you’ve spotted one in your home, you need to act fast before a full-blown infestation sets in. The good news? You don’t always need a pro to rid your home of these rodents. With the right type of rat poison or trap, many homeowners can handle a minor infestation themselves.
Expect to spend $10–$30 on store-bought poison baits or $25–$50 on quality traps. If the problem grows or you want to skip the hassle, professional rat extermination usually costs between $150 and $500, depending on the severity of the infestation.

In this guide, we’ll discuss the most effective types of rat poison, from anticoagulants to fast-acting neurotoxins, and share tips for choosing safe, pet-friendly alternatives. We’ll also explain when it’s best to go DIY and when it’s smarter to call a pro.
Chemical Rat Poisons
Chemical rat poisons can eliminate rats quickly, but they come with serious safety concerns—especially if you have pets or children. If you decide to use them, always follow label directions and use tamper-resistant bait stations.
Anticoagulants
Anticoagulants are the most common type of rodenticide. They kill rats by preventing blood from clotting, causing internal bleeding over several days. Popular active ingredients include brodifacoum, diphacinone, warfarin, and bromadiolone. These poisons typically require multiple feedings to be lethal, but second-generation versions can kill after just one dose. One well-known option is the JT Eaton 709-PN Bait Block, which uses peanut butter-scented blocks to attract rats. These poisons are effective but slow-acting and especially dangerous to pets and wildlife if misused.
Bromethalin
Bromethalin is a fast-acting neurotoxin that targets a rat’s brain and liver. It builds up fluid in the central nervous system, leading to death within 24 to 36 hours after ingestion. Unlike anticoagulants, it doesn’t require multiple feedings. A commonly used product is Tomcat Rodenticide with Bromethalin. Because of its potency, bromethalin poses a high risk to non-target animals and should be used with extra care or avoided entirely in homes with pets.
Cholecalciferol
Cholecalciferol, or vitamin D3, raises calcium and phosphorus levels in a rat’s body to toxic levels, leading to kidney and heart failure. According to the National Library of Medicine, it has some of the highest mortality rates among rodenticides. Products like d-CON bait pellets use this ingredient and can kill a rat within a few days. While it’s less risky to wildlife through secondary poisoning, it’s still extremely toxic if consumed directly by pets or children.
Zinc Phosphide
Zinc phosphide reacts with stomach acid to release phosphine gas, a lethal compound that kills rats within a few hours to days. It’s effective in outdoor or agricultural settings but is rarely recommended for residential use due to its extreme toxicity. Even small doses can be fatal to pets, people, or scavengers that come into contact with a poisoned rat.
Alternatives To Rat Poison
If you have kids, pets, or just want to avoid using toxic chemicals, there are safer ways to deal with a rat problem. While poison is effective, traps and non-lethal methods can be just as successful when used correctly, especially for small infestations.
Box traps are a humane option that lets you catch and release rats without harming them. You bait the trap, and when the rat enters, the door closes behind it. Once trapped, take the rat at least two miles away before releasing it. This method is great for homeowners who prefer not to kill animals, but it requires regular monitoring and a solid prevention plan to stop rats from coming back.
Snap traps are the old-school standard. They’re cheap, reusable, and effective when placed in high-traffic areas. Just make sure to use a trap designed for rats, not mice, because rats are bigger and require more force for a clean kill. For the best results, use peanut butter as bait and place traps flush against walls where rats travel.
Electrocuting traps are more expensive but provide a quick, humane kill. These battery-powered units deliver a high-voltage shock that kills the rat instantly. They’re easy to empty and reset without touching the rodent, making them a cleaner option than traditional traps.
Glue traps use a sticky surface to catch and hold rats. While they’re widely available, they’re controversial because they don’t kill instantly and can cause prolonged suffering. Use these only as a last resort, and never leave them where pets or children can access them.
If you’re not sure which method to try first, start with snap traps or enclosed electronic traps. They’re affordable, safe when used properly, and don’t involve any poisons that could put your household at risk.
Is it Legal to Buy Rat Poison?
Yes, rat poison is legal to buy, but there are restrictions on the type and packaging. According to the United States Environmental Protection Agency, pellet-style bait products are banned for residential use. Any poison sold to homeowners must be in block or paste form and packaged inside an EPA-approved bait station. These products are also limited to no more than one pound of bait per container. While these rules won’t affect most casual buyers (e.g., average homeowners) it’s important to double-check the label and only purchase products that meet current EPA standards.
How To Dispose of Dead Rats
Removing a dead rat quickly is important to avoid health risks. Always wear rubber gloves when handling a carcass. Spray the body and surrounding area with disinfectant before placing the rat in a plastic bag. Seal the bag carefully, avoiding any air compression that might spread bacteria. If you’re using a single-use trap, throw it out too. For reusable traps, disinfect and store them safely. Double-bag the carcass before tossing it in your outside trash bin, and take the garbage out promptly. Keep your gloves on while washing your hands with disinfectant, then remove the gloves and wash your hands again with soap and warm water.
How Do I Get Rid of a Rat That’s Still Alive?
If you catch a rat in a box trap, it’s likely still alive and needs to be released safely. Wear rubber gloves before handling the trap, then check to confirm the rat is contained. Place the trap in a sealed container like a bucket or box, and drive it at least two miles away from your home to prevent the rat from returning. When you reach the release point, turn the trap upside down to allow the door to open away from you, so the rat can run in the opposite direction. Once you’re back home, clean the trap thoroughly, discard any droppings, and store it for future use. Keep gloves on while disinfecting, then throw away the gloves and wash your hands thoroughly.
Symptoms of Rat Poisoning
If you believe your child or pet accidentally ingested rat poison, look for the following symptoms of rodenticide poisoning. Note that symptoms may vary based on the ingredients in a poison.
- Lethargic movements or intolerance to exercise
- Coughing and difficulty breathing
- Weakness or dizziness
- Nausea or vomiting
- Nose bleeds or visible blood in urine or stools
If your child or pet is experiencing any of these symptoms, contact a poison control center immediately or call 911.
How To Prevent Future Rodent Infestations
Rats are most likely to invade in the fall and winter when outdoor temperatures drop, and they start searching for food and warmth. The best way to avoid an infestation is to make your home as uninviting as possible before they even show up.
Start by eliminating access to food and water. Clean your kitchen regularly, sweep up crumbs, and avoid leaving pet food out overnight. Store dry goods in sealed containers, and fix any leaking faucets or pipes that could provide moisture. If there’s nothing for rats to eat or drink, they’re far less likely to stick around.
Next, secure your trash. Make sure garbage bags are tightly tied and kept in sealed bins—both indoors and outdoors. Rats are drawn to the smell of food waste, and even one open bag can attract them to your property.
Inspect your home for entry points. Rats can squeeze through gaps as small as a quarter, so check around windows, doors, vents, and your foundation for cracks or holes. Use steel wool or hardware cloth with caulk or sealant to block them—foam alone won’t stop rats from chewing through.
If you’ve dealt with rats before, or you’re in an area where they’re common, consider having a pest control pro inspect your home. An experienced technician can point out vulnerabilities you might miss and help you come up with a long-term prevention plan.
Routine maintenance goes a long way. By staying ahead of seasonal changes and keeping your home clean and sealed, you can drastically reduce your chances of seeing rats in the first place.
Should I Hire a Rat Exterminator?
If you’ve tried traps or poison and rats keep coming back (or if you’re dealing with more than a couple) it’s time to bring in a professional. A certified pest control company can quickly assess the size of the infestation, locate hidden nests, and treat the problem using stronger, targeted methods.
Most exterminators charge between $150 and $500 for rat removal, depending on the severity of the infestation and the number of visits needed. That price usually includes inspection, baiting, sealing entry points, and follow-up service. However, if your home needs major sealing work or if rats have damaged the attic or walls, the cost can go higher.
Professionals also offer long-term prevention strategies that go beyond store-bought traps or baits. Many companies now use eco-friendly or pet-safe solutions alongside traditional treatments, so you can ask about safer options if you’re concerned about pets or kids.
Generally, if you see signs of a full infestation — like droppings in multiple rooms, scratching noises in the walls, or chewed wires — skip the DIY route and call a pro. It’s faster, safer, and often cheaper in the long run.
So, What Are The Best Rat Poisons?
The best rat solutions depend on how many you’re dealing with, whether you have pets or kids in the home, and how comfortable you are using chemical products. For most homeowners, a combination of traps and bait is the most effective DIY approach. If you’re going the chemical route, products with anticoagulants like JT Eaton bait blocks or fast-acting options like d-CON pellets (cholecalciferol-based) are reliable choices. Just make sure to use these with the utmost caution.
For safer alternatives, enclosed snap traps, electronic traps, or rodent-safe baits like RatX can be just as effective without the risks that come with poison. And if you’re seeing signs of a growing infestation, or if traps just aren’t getting the job done, hiring a pest control professional is well worth the investment.
Frequently Asked Questions
To safely dispose of a dead rat, you’ll need rubber gloves, disinfectant spray, plastic bags, and soap and water. Dead rodents can carry dangerous bacteria and viruses, so always handle them with care. Start by putting on gloves and spraying both the rat and the surrounding area with disinfectant. Place the rat in a plastic bag, seal it, and then double-bag it before throwing it in an outdoor trash bin. If you’re using a reusable trap, disinfect it thoroughly before storing it away. After you’re done, disinfect your gloves before taking them off, then wash your hands well with soap and warm water. If you’re finding multiple dead rats, it may be time to call a professional pest control service, as that usually signals a deeper infestation.
The timeline depends on the type of poison used. First-generation anticoagulants like warfarin usually take four to seven days and require the rat to feed several times. Stronger second-generation poisons such as bromadiolone or brodifacoum can kill rats in just one feeding, usually within one to three days. Non-anticoagulant options like bromethalin and cholecalciferol work even faster — sometimes within 24 to 48 hours. Keep in mind that rats often crawl into hidden areas to die, so be ready to locate and remove carcasses to avoid odor and health risks.
Yes, rat poison can harm any animal that ingests it, and this is a serious issue with most chemical rodenticides. Many predators, including hawks, owls, cats, and dogs, can suffer from secondary poisoning after eating a rat that’s already ingested poison. This is especially common with second-generation anticoagulants, which stay in the rodent’s system longer. To reduce the risk, use enclosed bait stations and avoid scattering poison outdoors. Traps are usually a better choice if you have pets, live near wildlife, or want to minimize environmental impact.
There are several safer options on the market that can be effective without putting kids or pets at risk. Brands like RatX, MouseX, and RatRid use natural ingredients that are only lethal to rodents and pose no danger to humans or animals. Enclosed snap traps are another great option since they kill instantly and prevent accidental contact. Box traps let you capture and release the rat without any poison at all. Some homeowners also use ultrasonic repellents or scent-based deterrents to keep rats away, but these work better as a follow-up once the infestation is under control. If you’re worried about safety, it’s best to skip loose poisons entirely and use mechanical traps or enclosed bait systems.
