Invasive species wreak havoc on ecosystems, agriculture, and even our daily lives. Here are 25 invasive species that we wouldn’t mind seeing disappear forever, especially the gross ones.
1. Mosquitoes

While not all mosquitoes are invasive, species like the Aedes aegypti spread diseases such as Zika, dengue, and chikungunya. Their bites are itchy, and they pose serious public health risks.
2. Cockroaches

Cockroaches, particularly invasive species like the German cockroach, are notorious for infesting homes and spreading disease. Their resilience and rapid reproduction make them a persistent and revolting nuisance.
3. Locusts

Locust swarms can devastate crops and vegetation over vast areas. Their unpredictable and sudden invasions leave a trail of destruction and grossness.
4. Flying Ants

These bugs damage a wide range of crops and invade homes in large numbers seeking warmth. Their presence is both economically damaging and unpleasant, thanks to their odor.
6. Asian Giant Hornet

Known as the “murder hornet,” these large and aggressive insects pose a threat to both humans and honeybees. Their sting is extremely painful and can be deadly.
7. Argentine Ants

Argentine ants form supercolonies, outcompeting native ants and other insects. Their vast networks can disrupt local ecosystems and invade homes, creating an unwelcome, crawling presence.
8. Feral Hogs

Feral hogs cause extensive damage to crops, landscapes, and native wildlife. Their destructive rooting behavior creates havoc in both rural and suburban areas.
9. Cane Toad

Introduced to Australia to control pests, cane toads have become a significant problem themselves. Their toxic skin poisons predators, disrupting local wildlife populations.
10. Zebra Mussels

These tiny mollusks clog water intake pipes, damage boats, and disrupt local ecosystems. Their rapid spread and ability to stick to almost any surface make them a major nuisance.
11. Burmese Pythons

In Florida’s Everglades, Burmese pythons prey on native wildlife, leading to drastic declines in populations of small mammals. Their presence upsets the natural balance of the ecosystem.
12. European Starling

Introduced to North America in the 1890s, European starlings outcompete native birds for nesting sites and food. Their aggressive behavior and large flocks are problematic for both ecosystems and agriculture.
13. Emerald Ash Borer

This beetle has devastated ash tree populations in North America. Its larvae burrow into the bark, cutting off the tree’s nutrient flow and ultimately killing it.
14. Nutria

These large, semi-aquatic rodents damage wetlands by eating vegetation and burrowing into levees and banks. Their destructive habits threaten water management and natural habitats.
15. Japanese Beetle

Cogongrass is an aggressive invader that displaces native plants and alters fire regimes. Its rapid spread and dense growth make it difficult to control.
18. Gypsy Moth

Asian carp have invaded many U.S. waterways, outcompeting native fish for food and habitat. Their rapid reproduction and voracious appetite are major ecological threats.
22. Water Hyacinth

This floating plant clogs waterways, impedes boat traffic, and disrupts aquatic ecosystems. Its rapid growth can completely cover lakes and rivers, blocking sunlight and depleting oxygen.
23. Kudzu

Known as “the vine that ate the South,” kudzu spreads rapidly, smothering native plants and trees. This aggressive vine covers entire landscapes, making it hard for native vegetation to survive.
24. European Green Crab
