11 Bed Bug Bed Bug

Lol. I had no idea those were real.

12 House Cat House Cat

House cat because they're one of the worst invasive species. House/domestic cats are responsible for killing off many small animals of endemic islands (Australia, Hawaii, New Zealand, etc) to extinction. Don't let that cuteness cool you, cats have mostly negative impact towards almost all small animals of all islands due to predation on species that naturally never experienced many predators. The world would be better off without domestic cats. - DinoLover4242
