Do solar bed covers attract or deter insects and pests from my pool area, and how does this affect pool cleanliness?

Question

Tyler Smith · Accepted Answer

The impact of solar bed covers on insect and pest activity around pools is a common concern among buyers. While their primary role is [heating pool water and reducing evaporation](/qa/how-do-solar-bed-covers-affect-pool-water-temperature-and-swimming-season), their presence also influences the local ecosystem.

Deterrence Benefits

A solar bed cover acts as a physical barrier, significantly deterring debris and surface-dwelling insects from entering the pool water.

• Blocks Debris: The cover keeps out leaves, twigs, and other larger debris, which helps maintain water clarity and reduces the workload on your skimmer and filter.
• Repels Surface Insects: Many types of flying insects that might otherwise land on the water's surface are kept away.
• Reduces Mosquito Breeding: By covering the water surface, a solar cover limits access for egg-laying insects like mosquitoes, making the standing water less appealing as a breeding ground. This direct physical barrier offers excellent debris protection and helps manage the organic load in your pool.

Potential for Indirect Attraction

While the cover itself doesn't typically 'attract' pests, the environment it creates can sometimes be inviting to certain small creatures.

• Warmth and Shelter: The warmer, covered environment under the cover, especially during cooler nights, can offer refuge for small invertebrates seeking warmth or shelter. However, these instances are generally isolated, not problematic, and are more a consequence of local environmental conditions.
• Temporary Refuge: Tiny insects or spiders might find temporary refuge on the underside of a well-fitted cover if small gaps exist at the edges.
• Poor Maintenance Issues: If debris or algae accumulate on top of the cover due to inadequate [cleaning and maintenance](/qa/how-do-i-clean-and-maintain-my-solar-bed-cover-to-prevent-algae-or-mold), this could inadvertently become a breeding ground for some organisms or attract pests.

Impact on Pool Cleanliness

The overall impact of a solar bed cover on pool cleanliness is overwhelmingly positive.

• Reduced Organic Load: By significantly reducing the influx of external debris and many types of insects, solar bed covers diminish the organic load in your pool.
• Lower Chemical Usage: This reduced load means less work for your sanitizers (like chlorine) and filtration system, leading to clearer water and potentially reducing your [pool chemical consumption](/qa/how-do-solar-bed-covers-impact-pool-chemical-consumption-and-water-clarity-do-i-need-less-chemicals).
• Maintenance is Key: Regular cleaning of the top surface of the solar bed cover is essential to maximize these benefits and prevent any indirect attraction of pests due to accumulated organic matter.

Based on extensive user experiences, the debris-blocking benefits far outweigh any minor, indirect pest concerns. The positive impact on pool cleanliness and maintenance is a significant advantage.
