When you spot a cockroach or ant trail, the first instinct is to grab a can of insecticide. While DIY has its place, knowing when to call professionals saves time and money.
When DIY Works
- Single sightings — One cockroach doesn't necessarily mean infestation
- Prevention — Sealing gaps, maintaining cleanliness, basic deterrents
- Common pests — Occasional fruit flies, a lone lizard, booklice
- Outdoor areas — Garden ant treatment, mosquito repellents
When to Call Professionals
- Recurring pests despite DIY efforts
- Evidence of nesting (egg cases, ant trails into walls)
- Health-risk pests (bed bugs, dengue-area mosquitoes, rodents)
- Structural pests (termites — immediate professional assessment needed)
- Business premises requiring NEA compliance
Cost Comparison
- DIY sprays: $10-50 per application, often repeated without resolution
- Professional one-time: $80-300 depending on pest and property size
- Maintenance plan: $50-150 per month with guaranteed results
- Cost of NOT treating: Thousands in damage, medical bills, or business losses
What Professionals Bring
- Expert species identification
- Professional-grade products
- Integrated prevention + treatment approach
- Safety and proper application
- Warranty with free re-treatment
