In Arizona, the Arizona Bark Scorpion is the primary health concern — its sting can cause serious symptoms requiring medical attention, especially in children and elderly adults. Other scorpion species in Pima County produce painful but not medically significant stings. Professional scorpion control involves both targeted treatment and structural exclusion: sealing gaps at the foundation sill, weatherstripping, and eliminating harborage areas around the perimeter.

Ant infestations return when the colony is not eliminated — only surface foragers are killed — or when entry points are not sealed after treatment. Most ant species will relocate the queen and establish a new foraging route within days if the original route is treated with repellent products. Non-repellent baiting that targets the queen and colony is substantially more effective for long-term control than contact sprays that only affect foraging workers.

Ant baiting places a delayed-action insecticide in a food matrix that worker ants take back to the colony and share with nestmates and the queen through trophallaxis — the regurgitation of food shared between colony members. Because the bait is carried to the colony rather than applied to the colony location directly, it reaches the queen and reproductives that repellent treatments never contact. Colony elimination, rather than worker suppression, is the goal of baiting programs.

Worker ants locate and consume bait, carrying it back to the colony where it is shared through regurgitation with other workers, larvae, and queens. The active ingredient acts slowly enough that workers distribute it broadly before dying, maximizing the number of colony members exposed. Effective bait programs require using the right food matrix — sugar-based or protein-based — matching the target species' current nutritional preferences.

Consumer-grade ant bait products work for minor infestations but are often less concentrated, use less attractive food matrices, and are available in quantities insufficient for significant infestations. More importantly, most consumer baits are formulated for a broad species range rather than the specific species present in your home. Professional-grade baiting programs use species-targeted products and multiple food matrices simultaneously to maximize uptake.

Odorous house ants and pavement ants nest in wall voids, insulation, under flooring, and beneath slab foundations. Carpenter ants nest in moist structural wood — behind wall cavities with plumbing leaks, in window frames, and in attic framing affected by roof leaks. Ant nests inside structures are satellite colonies dependent on a parent colony usually located outside; eliminating indoor activity often requires treating both the indoor satellite and the outdoor parent colony.

Pavement ants are not medically significant — they can sting but rarely do. Their primary nuisance is foraging into structures through foundation cracks and slab penetrations in search of food. They nest in soil beneath slabs, in foundation cracks, and along building perimeters. While structurally harmless, large pavement ant populations foraging through kitchens and food storage areas represent a sanitation concern.

Foundation perimeters concentrate the conditions ants seek: moisture from irrigation and roof runoff, warmth from the structure, and direct soil contact providing nesting opportunities. Mulch beds against the foundation retain moisture and provide harborage. Pavement ants, odorous house ants, and carpenter ants all commonly nest at or near foundation perimeters and use foundation cracks and utility penetrations as entry points to access interior spaces.

Broadcast bait applications over lawn and landscaped areas are the most effective yard-wide ant control method. Granular baiting products are carried by worker ants back to colonies distributed across the yard surface. For fire ants specifically, individual mound treatment eliminates active mounds while broadcast bait suppresses the broader yard population. Professional applications calibrate product selection and coverage to the species present and yard conditions.

When a scout ant locates a food source, it deposits a trail pheromone while returning to the colony. Other workers follow this chemical trail, reinforcing it with their own pheromone on the return trip. The strength of the trail intensifies as more workers use it, directing foraging effort toward productive food sources. Trail pheromone is the mechanism that converts a single scout finding crumbs in a kitchen into hundreds of workers within hours.

Most ant species are structurally harmless. Carpenter ants are the exception — they excavate moist wood to create nesting galleries, causing structural damage in wood framing, window frames, and wooden decking. Fire ants occasionally damage electrical equipment by nesting around junction boxes and circuit breakers. Argentine and odorous house ants cause primarily nuisance and sanitation concerns without structural implications.

Spring ant swarms in Arizona are produced by established colonies releasing winged reproductive males and queens — alates — to mate and found new colonies. Swarm timing is triggered by warming temperatures following winter, often coinciding with the first warm days after rain. Seeing ant swarmers indoors in Arizona spring months typically means a mature colony is already nesting in or near the structure. Swarmers themselves do not sting or bite and represent a temporary event.
