There are a list of them on my links page in the 3rd column. Most of them are okay as all have to be licensed by the NEA and have to undertake training. However, having said that, it's good to find out what types of chemical and baits they use. I would compare rates but don't go for the absolute lowest rate out front. Most can come down a bit. As I am affiliated with a fairly large pest control company, I will refrain from making any suggestions as any recommendation from me will be tainted.
And yes, my company is in the list as well as others. Most
condos usually have maintenance contracts with a pest control company already. Check with yours to ensure and to see what services they provide.
