8 Some of the Deadliest Pests in the Philippines You’ll Ever Encounter

Some of the Deadliest Pests in the Philippines You’ll Ever Encounter

Somehow we think that pests exist simply to annoy us. However, some of these guys have characteristics that are dangerous and even fatal to humans. In normal situations, infestations in your home can be solved by simply calling the right exterminators, termite control for termites or ants and so on. These homicidal vermin, though, require a different kind of professional for the job. Luckily, you can easily contact these guys should the need arises.

You shouldn’t wonder why there are such deadly vermin existing near you. After all, the Philippines is a country rich in wildlife, and many flora and fauna not found elsewhere lives here. Let’s take a look at some of its most dangerous members.

Box Jellyfish

If you’re a fan of Spongebob Squarepants, then you’ll know how much he loves “jelly fishing.” But just because the jellyfishes in the show are kind of friendly (they ‘playfully’ jolt the characters with electricity from time to time) does not mean they are in real life. The box jellyfish has been known as the world’s most venomous creature, although there are only few deaths recorded in the Philippines. Locals use vinegar to remedy the stings, but this practice was being discouraged in light of new evidence that vinegar can worsen the pain. Better watch out for these guys whenever you decide to go to the beach.

Cane Toad

The cane toad is feared for its skin, which is highly toxic to humans. It has two main chemicals: bufotoxin and bufotein; both are dangerous to animals and humans and is classified in many countries as a Class 1 drug alongside heroin and cannabis. These frogs aren’t native in the Philippines. It was introduced in 1930 as a means to eliminate pests in sugar plantations. Since then they have bred and multiplied, and Filipinos commonly call it the bullfrog.

Philippine Cobra

Known by Filipinos as the dreaded ulupong, the Philippine cobra possesses very potent venom that can cause respiratory paralysis in its victims. Symptoms include headache, nausea, vomiting and difficulty in breathing. If left untreated, it can result in complete respiratory failure and in many cases death. The Philippine Cobra is mostly found the Luzon, most particularly in provinces like Catanduanes, Masbate and Mindoro. Every now and then, one of these snakes can make an appearance in someone’s bathroom or attic, causing panic all over the neighborhood.



Rats have been known as a disease carrier for many centuries, not only in the Philippines but in other countries as well. Look up the Black Death in Europe or the infamous Rat Flood in India in case you’re feeling skeptical about it. In the Philippines, one of the most popular diseases rats bring is Leptospirosis, which can make your skin yellow and give you kidney failure. Luckily for you, there are many ways to get rid of these rodents.



Dengue fever is still a prevalent disease in the Philippines, and it’s usually spread through mosquito bites. Majority of its victims are children ages 5 to 14 years old and more than half of them are male. The government has introduced many prevention methods in order to eradicate this threat. This includes water treatments and makeshift hospitals in certain circumstances. As of now, there is still no approved vaccine for dengue fever.

As you can see, three of these pests are rare and you’ll rarely encounter these guys, while the other two could be lurking in your home even at this moment. Better take the necessary precautions against these guys immediately!

  1. Hello, I ‘m wondering about the most common snake or cobra you will find west of the Zambales mountain range in central Luzon. ‘ We live farely close to the salt water/fish ponds and the neighbor just killed a 5 footer that looked just like this pictured Philippine cobra. Also it looks like pictures of so many King Cobra. I saw a snake go down a hole that seemed to have a tail about thee feet long. Real skinny and slender… It sure would be nice to know. I just wished my wife wouldn’t spend so much time out pulling weed and comoti leaves.in the dark.

  2. Hi, just further to your information on box jellyfish. There have been considerably more than a few deaths recorded in the Philippines caused by box jellyfish. Experts estimate 40 each year, but no-one actually knows as official surveillance and reporting across 36,000 kms of coastline is virtually non-existent. The Washington Post quoting Dr Angel Yanagihara in a 6 July 2019 article estimated between 100 – 500 deaths each year. The point is, no-one really knows, but anecdotal evidence suggests that it is a lot. In terms of vinegar, it remains the only means of guaranteed treatment and is accepted as such around the world. Dr Jamie Seymour’s theory (2014) that vinegar makes the situation worse has been disproven and discredited by his peers. Vinegar is not associated with pain management, its function is only to stop stinging cells on tentacles from firing venom into the skin.
