In Dubai, daytime temperatures soar above 40°C, and humidity increases in the evenings, which is an ideal environment for mosquitoes. That is why pest control for mosquitoes is frequently required, as these conditions turn quiet gardens, parks, and even homes into thriving habitats for mosquitoes. So, understanding why these pests multiply during the hot months is important so that you can counter this issue by being more proactive.
Reasons for Mosquito Surges in Dubai Summers
Dubai’s summer, typically from June through September, creates a unique environment that boosts mosquito populations. The following factors create conditions that make mosquitoes more active and annoying:
1. Increased Humidity
Watering lawns and flower beds raises humidity and dampens the soil, creating ideal conditions for mosquitoes. As humidity peaks, they fly more often, bite more aggressively, and lay more eggs. This nonstop cycle sustains high numbers throughout the season.
Similarly, humidity-laden wind streams from the Persian Gulf also raise relative humidity across the city. These gentle breezes carry mosquito eggs and adults from coastal wetlands into urban zones.
2. Urban Heat Island Effect
Dubai’s cityscape of glass and concrete absorbs and radiates heat. Buildings, roads, and sidewalks can remain 5–10°C warmer than nearby desert sands. This urban heat island effect keeps air and surface temperatures consistently high, even at night. Mosquitoes exploit these pockets of residual warmth to stay active longer, almost round-the-clock, which gives them more opportunities to feed and multiply.
3. Extended Warmth Leads to Constant Activity
Dubai’s summer days stretch long, often exceeding 14 hours of daylight and warmth. Mosquitoes remain active from just before sunset well into the night because air temperatures rarely drop below 30°C. Constant warmth lets female mosquitoes seek blood meals and lay eggs every two or three days instead of weekly.
4. Scarcity of Natural Predators
Summer’s extreme heat drives away many birds, bats, and amphibians. They either leave or reduce feeding near open water, limiting natural mosquito checks. Dragonflies, fish, and frogs normally consume larvae, but struggle in overheated, shallow pools. On the other hand, urban sprawl further reduces green corridors that support predator populations. So, very few natural enemies remain to curb mosquito numbers during the hottest months.
5. Water Collection and Condensate Pools
Split units, chillers, and window air conditioners expel water as they cool indoor air. Drain lines often discharge onto ledges or into unsealed drains, creating tiny pools. In summer, condensate flows nonstop for hours, offering constant habitats for larvae and fueling mosquito breeding around balconies and service areas.
Moreover, during summer, people store water to beat the heat, leaving drums and barrels open, which makes them ideal mini hatcheries.
6. Rapid Larval Development in High Temperatures
Warm water speeds up mosquito growth, so when water in puddles, planters, or drains heats more than 30°C, mosquito eggs hatch within two to three days. Larvae feed constantly, and the entire cycle from egg to adult can be completed in just seven days instead of two weeks. Now that is going to cause exponential population growth! And what happens is that this quick cycle fuels sudden spikes in mosquito swarms during early summer, catching people off guard.
7. Inner-City Construction Sites with Stagnant Water
Dubai is constantly going through developments, and there are construction sites throughout the city. So excavation pits, foundation trenches, and material storage areas collect rain or irrigation water. Without covers or pumps, these sites become large breeding pools. Moreover, due to the intense daytime heat, permits are granted for night construction, where the combination of lights and water also attracts adult mosquitoes for both breeding and feeding.
What to Do
High temperatures, humidity spikes, and man-made water sources all combine to fuel rapid breeding and constant activity.
