Rodents in house? Need help.

Every homemaker wants the house to be free from any outside invaders such as rodents, but despite the fact, and the best efforts of cleaning and organizing the house properly still rodents explore their way in our every day to day lives. My grandma lives in CT. She was complaining about rodents in her house. She said she tried Trapping, Poison Pallets, Predators, Repelling Devices. But the rodents were back again. She was asking for a pest control company that will resolve her problems. Someone near by them had told to call NYC Pest Exterminators professionals for their help.
