A termite infestation is usually discovered when:
a. When the colony number increases to 2000
b. Workers go back to the nest with food
c. All of the above
d. Reproductives emerge for mating flights
The Correct Answer and Explanation is :
The correct answer is:
d. Reproductives emerge for mating flights.
Explanation:
A termite infestation is typically discovered when reproductive termites, also known as alates or swarmers, emerge for their mating flights. This occurs when the colony has matured, and environmental conditions (such as humidity and temperature) are favorable. These swarmers are winged termites that leave the nest to find new locations to establish colonies. Their sudden appearance is often the first visible sign of an infestation to homeowners and property managers.
Why Not the Other Options?
- Option A: When the colony number increases to 2000 – Termite colonies can be quite large, often exceeding millions of individuals. A colony of 2,000 termites is still relatively small and unlikely to be noticeable because termites remain hidden within wood or soil. Homeowners typically do not detect termites based solely on colony size.
- Option B: Workers go back to the nest with food – Worker termites constantly forage for food and return to the nest, but this behavior is hidden within walls, wood, or underground. Since workers do not come out into the open, their activity is usually not the first noticeable sign of an infestation.
- Option C: All of the above – Since neither colony size nor worker movement is a typical first sign of detection, this option is incorrect.
How Infestations Are Discovered
- Swarming Termites – Seeing flying termites indoors is a major red flag.
- Discarded Wings – After mating, swarmers shed their wings, often near windows, doors, or light sources.
- Mud Tubes – Subterranean termites build shelter tubes on walls or foundations.
- Damaged Wood – Hollow-sounding or visibly damaged wood indicates termite activity.
Conclusion
While termites remain hidden most of the time, their swarming phase is when people first notice them. Thus, the correct answer is D: Reproductives emerge for mating flights.
