When we refer to the “field mouse,” it’s pretty much including every common mouse around the world. As we know, mice are common all over the world, regardless of the country you happen to be in. There might be a different look for some compared to others. Some might be black while others are brown or gray, you’ll even see some white types too. In other parts of the world, there could be a variety.
They are among the most notable invasive species mostly due to our issue with them as humans. They often invade our homes, eat parts of our food, and leave nice dark presents for us. The species is a menace to society and we’ll do anything to get rid of them. So much so, we’ll introduce creatures to regions to help limit the field mouse species in our area. Proving, we’d rather deal with another invasive species than mice most of the time.
The Malaria Mosquito obviously gets its name from what it tends to spread, the Malaria virus. While mosquitos are now common to see all over the world, this specific species of mosquito mostly can be found in Sub-Saharan Africa. Naturally, it became a notable invasive species simply due to what it carries. Mosquitos naturally bite into the skin of animals and humans alike, and that is something you’re going to see with them all.
The difference here is that the species has the Malaria pathogen. The moment it bites into a human or animal, it then transfers that very pathogen. Of course, some people do not get sick from this. This is especially true for those who spot the mosquito before it has time to really do anything. However, the rest may contract the virus and get very sick. There are vaccines to cut the symptoms down and nets to keep them away as much as possible. However, it is still not enough.
To be fair, deer are found worldwide. There are some in the species that have been introduced elsewhere, however. This includes the Red Deer, which was introduced to Argentina, Australia, and New Zealand. Yet the most interesting thing about deer is that they are actually invasive to the place they are native. While it is true that some have been introduced, a place like the United States of America has been seeing deer for several centuries. It’s native to this land. The Whitetail Deer, for example, is widespread.
Yet the population has gotten out of control, especially during the time of year when hunting deer is not allowed outside private land. In fact, hunters are only allowed a specific amount per hunting season too. This is to help keep the population from being reduced too heavily obviously. Yet deer reproduce heavily, causing millions to pop up every year. They have interrupted agricultural territories, and they are even known for causing more car accidents than any other species in America COMBINED. This makes them responsible for over 200 human deaths per year.
This is actually the only animal on the list that is not actually native to any region. Known as the Africanized Honeybee, they have been referred to as “Killer Bees” by most people for a long time. This is primarily due to the fact that they have actually been responsible for many human deaths. How is it that this species is not native to any area? Killer bees are actually a hybrid bee species. They are a cross between a Western Honey Bee and East African Lowland Honey Bee.
The species was bred to see if there might be an increase in honey production with two species that do this well…just in different ways. The species was introduced to Brazil in 1956, confined in a quarantined area. This changed when in 1957, 26 swarms of the bee managed to escape. They began to breed heavily, making their way through South & Central America. By the 1990s, they managed to make it into North America. Killer bees have been a notable invasive species there ever since.
