"Tapinoma sessile are actually invasive in an urban environment, despite being native." "And they are native, but can become invasive if conditions are right."
What does that even mean? Please define 'invasive' so that we can gain a better understanding of what you are saying.
"I've seen Tapinoma sessile get millions of ants in a period of two years."
How did you determine this? Have you ever bothered to do any testing to confirm the accuracy of your methods? Did you ever estimate a colony size and then dig it up to count every single ant to see if the reality matched your estimation?
(edited for obvious reasons to those who saw and its quoted anyway lol. If this wasn't a troll bait post, sorry, if not the old contents of this post didn't need to be on the forums anyway even if the quote is bait (or not))
"In natural areas, odorous house ants form small colonies and co-exist near the nests of other ant species, although they are never a dominant species. However, in urban areas, odorous house ants become dominant, and are found in close proximity with few, if any, other ant species. They form large polydomous colonies with huge numbers that out-compete other ant species for resources. Even though they are a native species, they can function as an invasive species in urban areas. Recently, they have been found in Hawaii, where they have the potential to become an invasive species."
