Things You Will Need
If you have a roach infestation, you can eliminate the roaches from most of the home with chemical foggers, but the television set may still harbor these unwanted squatters; thus, removing roaches from a TV requires a different method of eradication. On the other hand, if you don't have a roach infestation but have purchased a used TV that is overrun with these pathogen-spreading pests, you must act quickly to kill the roaches to prevent a full-on infestation of your home.
-
Put the TV in a plastic bag large enough to contain it.
-
Seal the bag off with a knot or using a twist-tie.
-
Place the bag in the freezer.
-
Wait 24 hours and remove the bag from the freezer.
-
Remove the television and discard the bag.
-
If roaches are still present, repeat these steps or consider consulting an exterminator.
