Our laptop is invaded by ants. Hubby is dealing with the pesky creatures since they began building their colony at the back of our computer table and then find their way inside the laptop. They slowly eat up the keypad causing some keys to malfunction. Hubby can’t do anything to get rid of the ants permanently. I believe an effective pest control like the Pest control Palantine can solve our problem with ants. Spraying kerosene gas to the source can only debilitate the ants, they crawl back after awhile. Does anyone know an effective and cost-friendly pest control?
