Pest control in Las Vegas is scorpions in the block, roaches in the tighter housing, termites at the soil, and pigeons on the tile. Bark scorpions use the cool side of a stem wall, stacked rock, and the gap under a garage door. German roaches take kitchens where houses are attached or where food and water stay available in a dry city. Subterranean termites still want wood and paper touching soil, even in a desert that looks too hot for anything to bother. Ants follow the drip line because it is the only damp soil on the lot. Crickets show up when a rare rain wakes them.
Name the animal before you ask for a spray. A scorpion call is harborages, lighting, and seals at doors and weep holes. A roach call is the kitchen, the bath, and what must be emptied before a visit. A termite call is evidence versus a preventive pitch: tubes, wings, or soft wood, stated honestly. Pigeons on a roof or under a carport are not a scorpion visit. Roof rats are less the default here than in an old citrus neighborhood in the Valley, but a messy palm or a dense ivy can still host them. Say what you actually found.
Ask whether exclusion is included. A treatment that leaves the garage gap and the eaves open will be a short victory. Ask how droppings get cleaned out. Ask what a return visit covers. Rock yards and block walls are habitat, so ask what you should move: rubble, irrigation that wets the foundation every night, pet food in the garage. A high-rise corridor and a tract slab do not get the same plan. Say which you are.
This is a hot dry valley, not a cabin town filling with mice at the first snow, though mice can still show up. Lead with the pest you saw. Call the number on this page.
