1. Carpenter Ants: The Wood-Damaging Intruders

Carpenter ants, often large and black, are known for their ability to damage wood. They don’t eat wood like termites, but they excavate it to create nesting galleries.


  • Large ants, typically black or reddish-brown
  • Presence of sawdust-like frass near nesting areas
  • Trails of ants moving between the nest and food sources

Prevention and Treatment:

  • Seal cracks and gaps to prevent entry
  • Trim vegetation touching the building
  • Address moisture issues to discourage nesting

2. Rodents: Unwanted Houseguests

Rodents like mice and rats can wreak havoc on properties, contaminating food and spreading diseases. They’re notorious for their ability to squeeze through small openings.


  • Gnaw marks on wood, plastic, and wires
  • Droppings around food sources or nesting areas
  • Squeaking or scampering noises at night

Prevention and Treatment:

  • Seal cracks, gaps, and entry points
  • Keep food in airtight containers
  • Use traps or seek professional help for infestations

3. Spiders: Web Weavers and Hunters

Spiders are both predators and, for some, a source of unease. While most are harmless, it’s essential to identify dangerous species like the black widow.


  • Eight legs and two body segments
  • Various sizes and colors
  • Webs or egg sacs in corners or dark areas

Prevention and Treatment:

  • Regularly clean and vacuum to remove webs
  • Seal gaps in doors and windows
  • Professional help for venomous species

4. Wasps and Hornets: Stinging Insects

Wasps and hornets can pose risks to individuals with allergies. They build nests in sheltered areas, often in eaves or trees.


  • Slender bodies with distinct yellow and black markings
  • Presence of nests, ranging from papery to enclosed combs

Prevention and Treatment:

  • Seal openings and potential nesting sites
  • Caution around nests; seek professional removal if needed

5. Bed Bugs: Nocturnal Nuisances

Bed bugs are notorious for their ability to hitchhike into homes, often through luggage or used furniture. They’re small, flat, and primarily active at night.


  • Small, reddish-brown insects
  • Tiny white eggs and shed skins
  • Red, itchy welts on the skin after sleeping

Prevention and Treatment:

  • Regularly inspect used furniture or items
  • Wash and dry bedding at high temperatures
  • Seek professional help for infestations
