The Invasion Of Rats


Rats have been known to thrive in the dark and multiply by the thousands. As a matter of fact, some urban legends say that rats can match the human population in certain areas of the world. In India, bamboo rats emerged from hiding every fifty years to eat crops and everything they find edible.

Rats can indeed be a worrisome invader when they come by the thousands. But they can also wreak havoc in the home. Rats have a very high birth rate, this is why they can reproduce quickly while hiding in the basement, the attic, or in hidden areas of your house or property.

Rats can eat a wide range of plant and animal food. They can eat fruits and vegetables, they can also eat meat. They will also gladly eat leftovers or food that has been allowed to rot in trash bins. If they live in your house, they will raid your trash, destroy pantries, and even go on top of tables and kitchen sinks.

Many international teams have spent millions to destroy rat populations. This is to protect other wildlife that have fallen prey to rats. Homeowners who want to protect their children, pets, gardens, and entire families, are also encouraged to do what they can to stop them from multiplying and spreading disease.

Things To Consider When Using Rat Poisons

When using rodenticides, keep in mind that rats by nature, have bait shyness. Since they cannot vomit, they will typically try small samples of an unknown food, and then observe its effects first before consuming more. This is why you might want to consider using the right poison at home.

Since rats tend to “sample” the poisons first, you might find rodenticides that will require multiple ingestions to work better than ones that are lethal upon the first exposure. This is because if the rat will sense something bad with a strong rodenticide, it will never try to eat it again.

It should also be noted that some rats have already developed resistance to some rodenticides especially those that are known as first generation anticoagulants. This means that their bodies have adapted to this poison, and that you might need newer formulations for better results.

Of course, when using rat poisons, you should also understand that when placed indiscreetly, the poison itself, or the food that has been laced with poison can become a danger to children and also to pets. Rat poison can look like candy, and having the chemicals come into contact with the skin or eyes is harmful.

Pets also have the tendency to be able to find the rat poison no matter how well it is hidden. This is why rodenticide products must be stored in a child-proof or pet-proof container and hidden securely out of their reach. When using food laced with poison, children and pets must be kept far away from it.

You should also take note of the fact that dead rats can also become health hazards. If they die while hidden, it can create an offensive odor in your home. The carcass can also attracts insects like flies and cockroaches. Most importantly, handling it can also put you at risk of exposure to the poisons you used.

The Different Types Of Rodenticides

There are a lot of rat poisons available in the market today. They can kill on contact, meaning the poison can take effect after a few seconds or minutes, or they can work over time. This means that the rat needs to be exposed multiple times before it will be killed. Both poisons can be used effectively.

  • Anticoagulants – Anticoagulant-based poisons can take effect over time, usually 1-2 weeks. It kills the rat by destroying the blood vessels and by inhibiting its ability to clot its own blood. The rodent will die due to internal hemorrhage or anemia. It is considered the most humane form of rodenticide.
  • Metal Phosphides – It is a fast-acting poison and it will kill the rodents within 3 days. It does this by creating phosphine gas inside the stomach of the vermin when ingested with food. This type of poison is ideal for rats who are resistant to anticoagulant-based baits.
  • Calciferols – Also known as vitamin D, it is important to us humans, but it can lead to hypercalcemia in rodents. This makes it toxic for them and it can cause death over time. What it does is that it increases calcium absorption in rodents and it will cause their organs to mineralize and shut down.
