Termites

Termites (order Blattodea, infraorder Isoptera) are social insects that feed on the cellulose found in wood, paper, and other plant materials. In Mexico, the most destructive species are the subterranean termite (Reticulitermes spp. and Coptotermes spp.) and the drywood termite (Cryptotermes brevis). They are known as "the silent pest" because they can destroy structures undetected for years, making them one of the most costly threats to any property.

Identification

Termites live in colonies organized into castes. Identifying them correctly, and telling them apart from ants, is key to acting in time:

• Size: from 4 to 15 mm depending on the caste.
• Color: translucent white workers; soldiers with dark heads; dark winged reproductives.
• Castes: queen, king, workers, soldiers, and winged reproductives (flying termites).
• Difference from flying ants: termites have straight antennae, a broad waist, and four wings of equal size; ants have a narrow waist and unequal wings.

Signs of infestation

Because they work out of sight, early detection depends on recognizing their traces. Periodically check for:

• Mud tubes: pencil-thick earthen galleries on foundations and walls; they are the signature of subterranean termites.
• Hollow wood: beams or frames sound hollow when tapped because termites eat the interior and leave the outer shell intact.
• Shed wings: piles of identical wings near windows and lights after swarming flights, typical in spring.
• Sawdust and droppings: small mounds of fine sawdust or pellets (frass) beneath furniture and frames, typical of drywood termites.
• Blistered paint or sagging floors: rippled or soft surfaces that reveal advanced internal damage.

Risks: the silent pest

The risk from termites is real and serious. A mature colony can consume several kilos of wood per day and, without treatment, compromise the structural integrity of a building within a few years. They weaken beams, columns, door and window frames, floors, and ceilings, and the damage is usually extensive before it is discovered, translating into costly repairs.

Although they do not transmit diseases directly, the deterioration of load-bearing elements can pose a significant safety risk. They are also often excluded from home insurance coverage, which makes prevention and early detection the most cost-effective response to this pest.

How Fucesa controls it

Effective termite control demands an accurate diagnosis and a plan tailored to the termite type and the construction, under an Integrated Pest Management (IPM) approach:

• Professional inspection: evaluation of foundations, structural wood, and soil-wood contact areas to identify the species and extent of damage.
• Chemical barriers: application of termiticides in the perimeter soil and activity points to create a protection zone against subterranean termites.
• Bait systems: underground bait stations that workers carry back to the colony, eliminating entire colonies, including the queen.
• Wood treatment: application of protectants and localized injection into affected wood; for drywood infestations, heat or microwave treatments can be used to eliminate termites without replacing the piece.
• Follow-up: post-treatment monitoring to confirm the colony has been eliminated and to prevent reinfestation.

Prevention

Reducing moisture and wood-to-soil contact is the best defense against termites:

• Moisture control: adequate ventilation, leak repair, and proper drainage around foundations.
• Wood-soil separation: avoid direct contact of structural wood, firewood, or garden furniture with the soil.
• Physical barriers: anti-termite mesh and construction design that hinders access from the subsoil.
• Periodic inspections: annual professional checks that catch activity before the damage becomes costly.

When to call a professional

At any sign of activity, mud tubes, hollow wood, swarms, or shed wings, it is best to act immediately: with termites, every month of delay increases the damage and the cost. Controlling an established colony is not a do-it-yourself job; it requires equipment, products, and experience to reach the entire colony.

At Fucesa we have more than 40 years of experience protecting properties in Toluca and the Bajío region, with our operations base in Toluca and a presence in Queretaro. We work in accordance with NOM-256-SSA1-2012 and use products and procedures backed by COFEPRIS, integrating inspection, treatment, and follow-up under Integrated Pest Management.
