Houseplants can be dengue breeding grounds if not careful: Doctor explains

Dengue fever, the illness that caused a high number of fatalities in the country and especially in Kerala this year, is transmitted to humans by infected mosquitoes.  Common safety measures against the mosquitoes include insect repellents, protective clothes, keeping doors shut, treating water sources, and fogging. However, a dengue breeding source many people don't suspect in our homes might be turning into a 'mosquito hotspot ' on our premises - houseplants. Dr Kelita George, Specialist in Community Medicine and Public Health at Mar Sleeva Medicity, Palai, explains. 

What spreads dengue?
Dengue is mainly spread by the Aedes aegypti mosquito, a 'daytime hunter' that bites during the day. They are easy to spot because of their small, black bodies with white stripes. 

Why houseplants can be risky
While continuous rains or a dry climate don't create ideal conditions for dengue spread, alternating spells of rain and sunshine do.  Coconut shells, tyres, old shoes lying on our open land, and more can all turn into breeding grounds around us. Often, people clean and empty such spaces while taking dengue prevention measures.

However, an unsuspected breeding ground is flower pots. Especially those with hardened soil can create an ideal space for mosquitoes to multiply. Sometimes, water collects in these pots, and they become perfect breeding grounds for mosquitoes. Mosquitoes lay eggs, turn into larvae, and grow comfortably in these pots.

What should be done?
Pour out water from flower pots at least once a week. The Kerala Dengue Prevention Campaign uses the term 'Dry Day '- which is often Fridays, Saturdays or Sundays to clean such water-collecting items. This can break the Aedes mosquito's breeding cycle. Ensure that water isn't stagnant in any space in your home or neighbourhood to stay safe from dengue fever.
