How Do You Know If It’s Time to Call a Pest Control Company?

You should call a pest control company when you notice persistent pest activity, property damage, health risks, or when DIY methods fail to work. Pests may be small, but they can cause serious issues—ranging from structural damage to allergic reactions and disease. Recognizing the early warning signs of an infestation can help you act before a small problem becomes a major headache.

Here are the clearest signs that it’s time to bring in a professional pest control service:

1. You Keep Seeing the Same Pests Over and Over

Seeing a single bug doesn’t always mean trouble—but seeing multiple pests repeatedly in the same areas is a clear sign of a larger problem. If you're spotting cockroaches, ants, spiders, or rodents more than once or twice, it likely means:

• A nest or colony exists nearby
  
  

• Your home provides the food, water, or shelter they need
  
  

• The infestation is growing behind the scenes
  
  

Recurring sightings—especially during the day—often indicate that pests are comfortable and reproducing inside your home.

2. You’re Finding Droppings, Smudges, or Damage

Pests often leave behind physical evidence. If you notice any of the following, it’s time to act quickly:

• Droppings: Small black pellets (rodents), specks (roaches), or dust-like waste (termites)
  
  

• Chew marks: On wires, cardboard, walls, or furniture
  
  

• Grease trails or smudges: Rodents often leave dirty streaks along walls
  
  

• Shredded paper or insulation: Used as nesting material
  
  

• Hollow-sounding or damaged wood: A warning sign of termite activity
  
  

These signs mean pests aren’t just passing through—they’re settling in.

3. You Hear Unexplained Noises in Walls or Ceilings

Scratching, gnawing, or movement sounds—especially at night—are often caused by rodents or wildlife nesting inside your home. Common hiding spots include:

• Wall voids
  
  

• Attics and crawlspaces
  
  

• Behind appliances or storage areas
  
  

These pests can chew through insulation, wiring, and even pipes, leading to expensive repairs and safety hazards.

4. You’ve Tried DIY Pest Control Without Success

Over-the-counter sprays, traps, and baits may offer temporary relief—but they often fail to solve the root of the problem. You may need professional help if:

• The pests return soon after treatment
  
  

• You’re not sure what kind of pest you’re dealing with
  
  

• The infestation appears to be spreading
  
  

Professionals have access to stronger, targeted treatments and the experience to locate hidden entry points and nests.

5. You Notice Property Damage

Some pests cause extensive physical damage, including:

• Termites: Destroy wood structures, flooring, and walls
  
  

• Rodents: Chew electrical wires (fire hazard), insulation, and furniture
  
  

• Carpenter ants or beetles: Tunnel through wood, weakening the frame of your home
  
  

If you find signs of damage, don’t wait—getting a pest inspection now can save you thousands in repairs later.

6. Your Family or Pets Show Signs of Health Issues

Pests can spread bacteria, allergens, and disease. Be alert to:

• Asthma or allergy flare-ups (common with cockroaches or rodents)
  
  

• Bites, rashes, or skin irritation (bed bugs, fleas, mosquitoes)
  
  

• Food contamination or strange smells near pantries or kitchens
  
  

If anyone in your home is experiencing unexplained symptoms or reactions, pest control might be a necessary part of your health and safety plan.

7. You See Evidence of Nesting or Egg Cases

If you notice egg sacs, spider webs, or rodent nests, you’re dealing with more than just a few stray pests. Infestations can grow quickly once reproduction starts. The sooner you act, the easier and more affordable it will be to eliminate the problem.

8. You’re Moving In or Out of a Property

Whether buying, selling, or renting, professional pest inspections are a smart move. They:

• Uncover hidden infestations
  
  

• Protect new homes from existing pest problems
  
  

• Prevent pests from following you to your next property
  
  

Some mortgage lenders and property managers may even require pest clearance reports before closing or occupancy.

9. You Live in a High-Risk Area

Homes near water, wooded areas, or dense urban settings are more prone to certain pests. You should consider calling a pest control company if:

• Your neighbors have infestations
  
  

• Your home backs up to nature or open land
  
  

• Your area experiences frequent pest surges during certain seasons
  
  

Routine pest control can act as a barrier against pests entering from surrounding environments.
