Rat 'em Out! in College Area is a San Diego rodent-control operation on El Cajon Boulevard, targeting the three stages homeowners need most: entry-point sealing, interior trapping, and full removal. The company launched in 2015 in the San Francisco Bay Area before relocating to the 92115 ZIP, bringing a rodent-proofing methodology built around the fact that rats and mice need only a nickel-diameter gap to enter a structure. Technicians start each job with a ground-to-roof inspection, identifying gaps at roofline intersections, foundation vents, and plumbing penetrations before sealing them with steel mesh and commercial-grade excluder materials. Tree-limb clearance is part of the protocol because roof rats can jump up to nine feet horizontally, and overhanging branches along El Cajon Boulevard's older residential lots create direct access to attics and eaves — a concern that sends the crew to coordinate trimming schedules with Hugo tree service for branch-to-roof clearance. Once exterior access is closed, snap traps and multi-catch stations go into attic spaces, wall cavities, and subfloor crawl areas, with monitoring visits continuing until capture activity drops to zero. The proximity to SDSU means Rat 'em Out! handles a steady volume of calls from the dense rental housing stock between campus and the 15 freeway, where aging multi-unit buildings share wall cavities that let rodent colonies migrate between apartments. Post-removal, the team clears contaminated insulation, droppings, and nesting debris, then treats affected surfaces to neutralize urine residue — work that runs in parallel with the attic restoration crews at Attic Construction when insulation replacement is needed. The operation covers rats, mice, squirrels, and raccoon exclusion across single-family homes, apartment complexes, and the commercial buildings that line the El Cajon Boulevard corridor through College Area.
