Tomcat: Tomcat Rat Poison is a single feed bait that can be used indoors or outdoors for rats. One thing to note about this product is it does not repel other animals from feeding off of it while still being effective over time with exposure to rainwater and sunlight so make sure there are no pets in your yard before putting any out!

D-Con: D-con rat poison, also known as diphacinone, was first introduced back in 1954 because of its effectiveness against rodents especially Norway Rats (Rattus norvegicus) but works well on Roof Rats too (Rats rufescens). D-Con is a single feed bait that can be used indoors or outdoors for rats.

Behavior: Tomcat Rat Poison, when ingested by a rat will kill them within 24 hours after being eaten while D-con takes at least three days but kills all types of rodents (rats/mice etc) with few exceptions where some may survive up until five days later.

If you have been noticing fresh droppings outside your home, chances are you have rats living in your walls, roof, or attic. If you think this is the case, then try to seal all openings and use a rat repellent spray as soon as possible!
In order for any rodenticide bait station to be most effective against rats it needs to have an enclosed space where rodents can enter but cannot escape from without being exposed to the poison inside.

When you use these products outside of their designated areas wearers typically discourage other animals from feeding on them while also allowing rainwater and sunlight exposure which will eventually break down the toxicant causing it not work effectively over time.

Active Ingredients

Tomcat contains Bromadiolone, which is a cholinergic agonist that inhibits the release of acetylcholine from nerve endings in synapses. This causes paralysis and death to be caused by respiratory.

D-con contains Brodifacoum as its active ingredient which acts similarly but specifically targets red blood cells preventing them from carrying oxygen throughout the body resulting in heart failure after ingestion or injection.

Target Pest

Tomcat bait kills all three rat & mice species, the Norway rat (Rattus norvegicus), roof rats (R. rattus) and house mice (Mus musculus). Also D-con bait kills all three species of rats in your house. Both are the safest bait station to use near children & pet in your house.


Tomcat comes with a bait station & the bait itself is mixed in a wax-based dough which makes it difficult for the rats or mice to carry off of the station. D-con comes with Bait Blocks that are easy and safe to use near children & pets.

Coverage Area

Both can be use in both indoor & outdoor areas. Tomcat can be used in any place with a rat problem, it is not limited to just one room or area of your house & outside as long as you have bait stations.

D-con has two different baits: The Bait Blocks and the D-Con Ready Stripes for indoor use only. There are many other Hing to consider before you choose the bait like Rat population, species of rat & number of rodents in your house.


in here we are going to talk about the Warranty of both products. Tomcat Rat Poison has a 30-day refund policy, but only of the bait is unused and in unopened containers. if you are not satisfied then also they return your money. D-con’s warranty on their product will depend on what type you buy from them as well as where it was purchased.

EPA Registration

Both D-con & Tomcat is registered by the US Environmental Protection Agency. Although you can check the product label to see more detail about it.

How D-con works

D-con kills the rats by entering their stomach. The active ingredient in D-CON is a white, delayed release capsule that delivers 0.0734 grams of Bromadiolone per bait to each rat as it eats and ingests the smaller bait pieces (about one cubic inch). You will see your first dead rodents appearing 4 or 5 days after feeding begins

How Tomcat works

Tomcat contains a meat-based bait, which is attractive to rats. Inside the bait are small particles of Bromethalin that cause death by ingestion. The active ingredient in Tomcat is 0.005 grams of bromethalin per kilogram (0.0027 ounces per pound).

Tomcat Bait Stations are made of heavy-gauge, invertible plastic. The stations have a strong door that locks into place to protect bait inside the station from children or pets and also prevent wildlife access. The rodent locates the bait station, crawls inside, and eat the bait. As the bait is eaten, a release mechanism triggers the door to open and allow access for other rats.

The rat dies from ingesting small particles of Bromethalin in Tomcat. You will see your first dead rodents appearing about one or two days after feeding begins with Tomcat Bait Stations.
