On July 3 and 4, 2026, Campo Grande (MS) hosts the 10th Municipal Health Conference. The event gathers sanitary authorities, health councilors, and the community at the Fetems headquarters to outline the new goals for the Unified Health System (SUS) in the capital. Among this year's central agendas are the direct impacts of global climate change on urban health, the alarming rise in recorded scorpion stings, and the strategic importance of residential physical barriers, such as professional insect screens, in controlling domestic pests.
Climate Change and the Proliferation of Scorpions in Campo Grande
Technical discussions at the 2026 Health Conference point out that thermal instability and sudden variations in humidity in Mato Grosso do Sul are altering the behavior of synanthropic fauna. The increased frequency of atypical heatwaves creates the perfect environment for the accelerated reproduction of the yellow scorpion (Tityus serrulatus).
Unlike other species, the yellow scorpion reproduces by parthenogenesis, a process in which the female generates offspring without needing a male. Under constant heat and a high food supply in the city's sewage system, the population of these arachnids grows exponentially, invading residential areas.
With heavy isolated rains and intense heat, street sewers flood, forcing scorpions to search for dry shelters. In this vertical migration, they invade residences through floor drains, gaps under doors, electrical conduits, and, primarily, through open windows and door openings.
🦂 Scorpions as the Leading Cause of Venomous Incidents
Data from the State Department of Health (SES) confirm that scorpions lead the statistics for venomous animal accidents in Mato Grosso do Sul. In children under 10 years and the elderly, stings can trigger systemic poisoning rapidly, requiring immediate administration of anti-scorpion serum at the capital's UPAs within the first hours of the sting.
The Food Link: The Chain between Insects, Cockroaches, and Scorpions
Municipal epidemiological surveillance emphasizes that combating scorpions requires, mandatory, eliminating their food sources. The yellow scorpion feeds primarily on cockroaches, flies, termites, and small mosquitoes.
A house with frequent insect or cockroach infestations acts as an olfactory attraction hub for these arachnid predators. When insects enter freely through residential openings, they establish a feeding ground that inevitably attracts scorpions into walls and furniture.
Installing barriers that prevent the entry of insects in kitchen, laundry room, and living room windows breaks this biological cycle. Without insects to hunt, scorpions will not establish themselves in the home, drastically reducing the likelihood of stings in bedrooms or common living areas.
Insect Screens as Physical Barriers for Home Safety
The main sanitary prevention guidelines discussed at Fetems include encouraging residential self-protection through mechanical barriers. While authorities perform chemical control in public sewers and manholes, physical home shielding is up to the homeowners.
In this scenario, custom-made insect screens assume a highly relevant preventive role, acting on two fundamental fronts:
- Absolute Aerial Sealing: Windows and balcony doors without screens are free passageways for flying insects that feed scorpions, and for the scorpions themselves, which scale textured external walls or nearby foliage.
- Breaking the Food Chain: The fine mesh of vinyl-coated fiberglass (with spacing smaller than 1.2 mm) blocks the entry of flies, mosquitoes, and cockroaches, drying up the food supply of venomous arachnids inside the home.
Unlike chemical insecticides (whose direct application on scorpions is discouraged by Sesau because it does not kill them and makes them more active and aggressive), insect screens do not pollute, are ecological, and remain fully protective for many years.
Emergency Protocol: What to Do in Case of a Sting?
If any resident suffers a scorpion sting, the health conference reaffirms that speed in seeking initial medical care is the decisive factor in avoiding severe complications or deaths.
🚨 Mandatory Steps in Case of a Sting:
- Simple Cleansing: Wash the sting site immediately with only water and mild soap.
- Applying a Compress: Place warm compresses on the site to help relieve intense local pain.
- Urgent Transport: Take the victim as quickly as possible to the nearest UPA (Urgent Care Unit). In Campo Grande, all UPAs are integrated into the distribution network for anti-scorpion serum.
- Avoid Dangerous Practices: NEVER tie the limb (tourniquet), do not make cuts to suck the venom, and do not apply chemicals or home remedies to the wound. This accelerates necrosis and worsens the clinical condition.
Conclusion and Health Experts Recommendations
The discussions at the 10th Municipal Health Conference of Campo Grande in 2026 consolidate the idea that smart prevention combines public responsibility with preventive domestic habits. Protecting home windows with professional insect screens represents a smart and definitive investment to shield your family's health against the threats of venomous animals and disease-carrying mosquitoes in our capital.
