A box of rodent bait costs a few dollars and promises quick results. It is no surprise that many people start there. But poison often causes more trouble than it solves, and this guide explains why. It is general information, and labels and local rules are the final word.
Problem one: it does not kill instantly.
Most baits work slowly. An animal eats the bait, feels ill and retreats to a quiet place, often a wall void, an attic corner or a crawl space. It may die days later in a spot you cannot reach. The smell can last for weeks.
This is the most common complaint we hear. The animal that was bothering you becomes an odor you cannot trace. Our odor control page explains how the source is found and removed.
Problem two: pets, children and wildlife.
Bait is made to be eaten. A pet or a child can eat it, and a pet can also eat a poisoned animal. Wildlife, including owls and other predators, can be harmed by eating poisoned prey. The EPA has restricted some rodenticide products for these reasons.
- If a pet may have eaten bait, call a veterinarian or a poison hotline immediately.
- Keep the packaging so you can describe what the product was.
- Never place bait where children or pets can reach it.
- Read the label and follow all of its rules.
The [EPA page on restrictions](https://www.epa.gov/rodenticides/restrictions-rodenticide-products) describes the limits on some products. Rules and labels change, so check the source for current details.
Problem three: it does not fix the cause.
Rodents come in through gaps and stay because of food and shelter. Poison addresses neither. A house with open entry points will draw new animals after the first group is gone, and the cycle begins again.
| Approach. | What it does. | Common problem. |
|---|---|---|
| Store-bought bait. | Kills slowly, away from sight. | Dead animals in walls, risk to pets. |
| Snap traps placed well. | Removes animals you can check and reach. | Needs checking and good placement. |
| Sealing entry points. | Closes the route in. | Needs a thorough inspection. |
| Sanitation and storage. | Removes food that draws animals. | Takes a change of habits. |
Mouse or rat does not matter yet. Describe the sign and we will sort out the rest together.
Dial (888) 686-4821What works better.
The sound approach has three parts. Find how animals get in, remove the ones that are inside and close the openings. A technician who does all three leaves you with a house that stays clear.
Trapping and removal deals with animals in the house, and exclusion seals it. If you already used bait, tell the technician where you placed it so it can be collected.
If you have already used poison.
Many people have. Do not feel bad about it, but do act on what you know. Collect any bait you can safely reach, keep pets away from the area and note where you placed it. If a smell appears, call so the source can be found.
For help right now, call the line. We will explain what to do and, if it is useful, send a technician.
A word on labels.
If you do keep any pest product at home, read the whole label before use, and keep it in its original container. Labels set out where a product may go, what to wear and what to do after contact. They are written for a reason.
Store products where children and pets cannot get to them, and never move them into unmarked containers. If you are unsure about a product, ask the technician when they visit.
Before you call: protect yourself from droppings
Written for householders, these steps keep dust and germs out of the air while you wait for a visit.
- A broom, a vacuum and a leaf blower are all the wrong tools for droppings and nests.
- Let air move through a stale crawl space or storage room for about thirty minutes before you begin.
- Bare hands have no place in this job. Wear gloves from start to finish, then wash.
- Soak, then wait, then wipe. About five minutes of contact time is what makes the disinfectant work.
- Tie the waste in a bag and place it in the household trash. A dead rodent is never lifted with bare hands.
- Medical guidance lies outside our trade. Symptoms after handling waste belong in front of a doctor, together with an account of the job.
Public guidelines behind this advice
Public documents sit behind the advice above. They set out general practice and rules, and none of them endorses us.
