Even if you’re not an entomologist, there are several red flags that should make you pause:
### 1. You’ve Never Seen It Before
If the insect looks unfamiliar — especially if you’ve lived in the area for years — that’s worth noting. Invasive species often stand out because they don’t resemble local insects.
### 2. It Appears in Large Numbers
A sudden surge of the same insect on trees, walls, or plants can signal a growing infestation.
### 3. It’s Damaging Plants or Trees
Wilting leaves, sticky residue, holes, or bark damage often point to destructive insects.
### 4. It’s Unusually Bold or Persistent
Some invasive or harmful insects show little fear of humans or return repeatedly to the same location.
### 5. Local Warnings Are Circulating
If you’ve seen recent alerts from local authorities or news outlets about a specific insect, take sightings seriously.
