We've seen these tricks. Make sure your service provider passes all checks.
Chemicals wear off in 6-12 months. No honest pest control company promises lifetime protection.
Pest control operators must have a valid license from the state agriculture department or IPCA membership.
You have the right to know what is being sprayed in your home. Legitimate operators show you the product.
A good company gives 3-6 month written guarantee per treatment. No written warranty = no recourse.
If you have kids or pets, you MUST know what's being used. Any refusal to disclose is a red flag.
R32 gas refill: ₹1,500-2,500. R410A: ₹2,000-3,500. R22 (old ACs): ₹1,200-2,000. Always ask which gas your AC uses before calling.

Ask for their Wireman's License issued by the Chief Electrical Inspector's office. Verify through the state electricity board. Licensed electricians carry an ID.
