This question came to my mind this morning because of a recent discussion with a friend, who had expressed happiness about the coming of the raining season. She advanced two reasons for her happiness.
When I woke up this morning, I found that it had rained in the night because the weather was cool and I also saw the grounds were wet. I loved it.
My friend’s first reason was that the heat being experienced lately due to the dry season will be reduced. Good! I agreed with this absolutely!
Her second reason was that there will be a reduction in mosquitoes. Hmmn! Reduction in mosquitoes?
This last reason sounds somehow to me. Nevertheless, I nodded to signify my agreement with what she said then because the reason sounds plausible even though I was not totally sure about the efficacy of the rain reducing mosquitoes. The reason sounds plausible because one will truly expect that mosquitoes because of their tiny nature may not withstand raindrops.
So, when I saw it had rained as I said earlier, I remembered that discussion with my friend.
Her first reason was obvious as the weather was so cool and refreshing. Her second reason was unverifiable yet and I was looking forward to the evening which is when the mosquitoes usually come out to verifying this.
However, curiosity got the better part of me, and I couldn’t wait any longer till evening.
In other to quickly clear my doubt about my friend’s claim that rain reduces mosquitoes, I decided to made Google my companion immediately and checked things up about the efficacy of rains reducing mosquitoes.
Immediately I typed in my question, “does rain kill mosquitoes?” in the Google’s search bar, it quickly, as usual, offered me other search terms related to the question I have typed. It offered the suggestion, “does heavy rain kill mosquitoes?”
This got me thinking that maybe it is heavy rain that kills mosquitoes, not light showers. I ignored Google suggestion and went ahead with my search, with the intention of checking Google’s suggestion up later when I am done finding an answer to my original question.
Below is the answer Google thought was best to the question I have asked.
“But a mosquito is very lightweight, so a raindrop only decelerates by 2 to 20 percent when it collides with the insect in midair, creating a force of about 50 to 300 mosquito weights—still a significant force, but because of the mosquito’s extremely strong exoskeleton, not enough to kill on impact, Hu says.”
Based on the foregoing, rain doesn’t kill mosquitoes. It only reduces mosquitoes ability to flying around to attack you when it is raining.
