Supertech Pest Control About Us Pests come in all shapes and sizes. They range from tiny hordes of ants to a single animal that has made your attic its new home. No matter the pest, it means that your El Cajon home or business has been invaded. This could result in minor conveniences, such as the sound of something rustling in your attic, to a significant hazard, like contamination or property damage. This is why Supertech Pest Control was created. To 1) eliminate pests from the homes and businesses of our El Cajon clients and 2) to minimize the damage that wildlife and insects can cause to a property.
