Rats

I live off of Chestnut Hill Ave and for the last 3 month the rat population is getting worst, I have try everything bait, snap traps, snap cages and now I turn to using electric trap and they seem to work the best, In the last 3 weeks have killed 16 in total, I have no idea where they are coming from they are all over. So Mayor do you think before you go running off to be governor maybe you can take care of running these rat out Cranston. For the property taxes we pay we should not have to live like this.
