Method 1: Using a bait

Baits are better than sprays as baits will kill the entire colony. Therefore, this is the perfect method to get rid of cockroaches in Tennessee.

Using an IGR helps ensure the roach nymphs don’t grow into adults. The American cockroach is a notoriously fast breeder among roaches in Tennessee. Using an IGR spray will keep it in check for you.

An IGR alters the internal hormones of roaches to molt. This way, the roaches can not transform into adults and fail to reproduce.

Method 2: Insecticide Spray or Roach Bombs

Insecticide spray or roach bombs are quick solutions for getting rid of cockroaches in Georgia. However, Insecticide spray kills roaches but does not destroy eggs; hence, we often start to see roaches again just after a few weeks.

To get rid of Tennessee cockroaches, seal all doors and windows, turn off ventilators or air conditioning and spray around all the corners and cockroach hiding places. Then, wait for 30 minutes before you ventilate the room.
