10 Pests That Thrive In Moist Environments
Singapore is one of the most humid countries in the world. Surrounded by water, and resting just one degree north of the equator, our daily lives are often besieged by waves of heat and moisture. This amounts to an average humidity level of 84% in Singapore. But, apart from the incessant sweating and uncomfortable stickiness, did you know that such high humidity and moisture also make us a hot spot for certain pests?
From repulsive cockroaches, destructive termites, to frightening centipedes and pervasive mould, Star Bugs gathers 10 pests that flourish in damp conditions. Uncover what they are and where they dwell, and stay until the end of the article for quick tips to reduce moisture and their presence!
1. Cockroaches
Inspiring much fear and disgust, cockroaches are among the most rampant moisture-dependent pests in Singapore. These critters proliferate quickly due to our densely packed urban environment and tropical climate. Attracted to dark and damp places, cockroaches can be found near leaking pipes, kitchen sinks, behind toilets and other areas where there is moisture buildup in the home. They are also ectothermic — meaning they rely on external heat to support their body functions.
2. Termites
Most termites live underground where there is sufficient moisture in their surroundings. In particular, termites favour damp or wet wood, although drywood termites are less reliant on the moisture content present within the wood they consume. While blistered or damaged wood can suggest a termite infestation, it also serves as an attractant to termites. Elevated levels of moisture and humidity provide a more suitable habitat for termites to take shelter in and chew through.
3. Ants
Similar to termites, ants are attracted to excess moisture, with certain species like moisture ants requiring a more humid environment to survive. Ants are less selective about where they build their nests, so they may settle anywhere from drains and laundry piles to areas around the kitchen sink. They typically establish their colonies in hidden locations with consistent temperatures and protection. This allows ants to maintain access to food and water sources while focusing their efforts on colony expansion.
4. Silverfish
Distinguished by its soft, shiny and silver body, the appearance of a silverfish is unmistakable, even with just a brief glimpse of its wiggling movement. While they primarily prefer to feed on carbohydrates and proteins, silverfish also have a liking for polysaccharides and starches, leading them to consume anything from paper and glue to fabric. Beware of moist and shaded areas where such materials can be found, as silverfish are prone to dehydration, receiving moisture directly through exposure to their exoskeleton.
5. Centipedes
Centipedes are venomous critters classified as invertebrates rather than insects. They have a long, flattened body and possess 15 pairs of legs or more. Unlike most other household pests, centipedes aren’t known to intrude intentionally, but can be attracted to dark and damp indoor spaces, leading to their discovery in bathrooms, kitchens and basements. They may enter your home through cracks and gaps in doorways and in between walls.
6. Millipedes
Like centipedes, millipedes are typically found outdoors, but can creep into your home if it offers adequate moisture. What sets millipedes apart from centipedes is their diet of damp and decaying plant-based matter such as rotting wood, leaves and fruit. Because of their high demand for moisture, millipedes tend to hide or curl up under objects during the day to avoid direct heat and sunlight.
7. Dust Mites
Maintaining a humidity level of less than 50% is required to reduce dust mites in the home. While these microscopic insects do not bite, they do cause allergies and rashes that can be harmful to those with sensitivities. Warm, humid environments that contain dead human skin cells make ideal living conditions for dust mites.
8. Drain Flies
Drain flies are small, furry, moth-like pests that can be seen swarming around kitchen sinks, bathrooms and even houseplants. These true flies favour decaying organic matter, especially in the presence of standing water and warmer temperatures. Not only do these settings provide drain flies with a food source, they also act as a suitable breeding ground for them. Some even say that drain flies can tolerate boiling hot water.
9. Mosquitoes
Most of us in Singapore know the requirements for mosquito growth like the back of our hand. Considered one of the deadliest insects on earth, these pestilent insects thrive in areas with water regardless of their genus, although some prefer reproducing in stagnant water more than others. The Centers for Disease Control and Prevention categorise these mozzies into permanent water mosquitoes and floodwater mosquitoes, with the latter preferring to deposit their eggs in areas prone to reflooding. It should also be noted that mosquitoes often emerge at sunrise and sunset, which present with warm (but not scorching) temperatures and wetter conditions.
10. Mould
Although mould is neither an insect nor an arthropod, it is a pervasive and common household pest that can cause significant damage to both your home and your health. This destructive fungus thrives in environments with heightened humidity, often due to excess condensation and inadequate ventilation. When dealing with mould, it is crucial to determine the precise cause of dampness, such as leaking plumbing or poor construction. Furthermore, aside from its direct effects, mould can also attract other pests that feed on it, such as cockroaches, termites and booklice.
Banish Dampness and Pests in Your Home
Moisture plays an active role in fostering the growth and spread of various pests. However, by taking effective measures to reduce moisture levels in our homes, we can control and curb the risk of pest invasions, even in a tropical climate like Singapore’s.
To start, identify and repair any leaks or seepage to eliminate water accumulation. Next, take note of areas where condensation may occur, such as interior walls or air conditioning units with drainage issues. Ensure proper ventilation to remove moisture, such as by opening windows and installing fans near bathrooms and kitchens, to promote air flow. Consider using dehumidifiers to absorb moisture in the air as well.
While these methods can be helpful strategies to minimise moisture and humidity, they may not be the complete solution to address an ongoing pest problem. If you are experiencing any moisture-related pest issues, from cockroaches and termites to silverfish, mosquitoes, and others, seeking prompt assistance is necessary to prevent the infestation from escalating.
