A Plague of Mosquitoes INSIDE Our House

 With the start of the Victoria Day long weekend here in Canada (and Memorial Day next weekend in the U.S.), I thought it only appropriate to talk about mosquitoes. This weekend many urban dwellers will travel to the nether regions of remote Canada to experience nature in all its beauty, and oh yes, mosquitoes and black flies will be part of the ambience.


Michelle wasn’t enthused about me writing this blog, but I think it’s an important one. Lots of people who live in the city read this blog and have their own dreams of living in the country. Ninety-nine percent of my blogs talk about how great country life is. But I’d be dishonest if I didn’t write the odd post talking about some of the downsides. One negative that comes to mind easily is how difficult it is to just zip off to your favorite restaurant on those nights when you don’t feel like cooking.

So this blog is about mosquitoes - not the ones outside of our house, but the ones inside. Right now the mosquitoes are much worse inside of our house than outside. Yes we have screens. Yes we keep our doors closed. But these ones come from within.

It’s a bizarre occurrence but it happens every year at this time. And I know what you’re thinking. The Mathers must have large bodies of standing water in their house for mosquitoes to hatch from. There must be puddles in their kitchen. That’s how I understand the mosquito lifecycle - they start in water. And yes our basement floods every spring, but this happens even when the basement isn’t flooded. One year there was a bit of water in the sump well, but we closely examined it and there was no sign of mosquito larvae. And I know what these look like because I see them in my rain barrels all the time.

So then I thought maybe they’re breeding in the septic tank (which is a stretch because surely mosquito larvae couldn’t exist in those conditions). But all the drains have traps -“S” shaped turns with water sitting in them – that would prevent the mosquitoes from getting up the pipes. The last time I checked mosquitoes aren’t able to fly part way, and then go aquatic to swim through the trap, then dry off their wings and fly again, like little mini-winged Jason Bourne’s. Our friend Robert mentioned that he gets some mosquitoes in his house too and he figures that they come in on the firewood and come to life when they thaw out. But we don’t have any firewood in the house right now.

Hi - just read your blog with great interest and would like to share this. I too had this overly large number of the little vampires in my cottage the other evening. After spending quite some time swatting I noticed some activity around my Resolute Acclaim wood stove. Curious I decided to "check this out". I opened the top of the stove and was immediately greeted with about 200 plus of the flying vampire insects the dispersed in every direction. I was shocked and jolted back to the invasion. After swinging, missing, and swatting I went outside (not as many mosquitoes out there) I looked up at my chimney and saw a black cloud of the suckers - obviously waiting to get down the pipe and into the cottage. I had never seen this before. I had made a fire in the wood stove a few days earlier, but had closed the flu etc after and all that remained in the stove was ash! They must have been finding passage in to the cottage area in through the grates of the stove a few at a time, that is until I opened the door for them. (how polite I am). Needless to say, I din't spend the night. Others didn't believe me so wanting to prove it I went back the next day with a friend and opened the door to the wood stove again - He is a believer. I have since stuffed insulation up the chimney - and covered the stove with a tarp. I'll go back in a few days and hope I have a mass of dead insects. Hope! Dan on the Chockpish River Bouctouche NB

Similar situation here... no guest house to retreat to... So you can imagine the rage-induced/sleep deprived mosquito hunt rampage that ensued.... Anyway. Led us to the bathroom vents. Previous owners installed an ensuite without putting mesh over the bathroom vent! A temp fix with window screen has helped tons. The other incoming route was the dryer vent! keeping the dryer closed when not in use, and turning it on briefly before opening it helps!

I used to run a movie theater at a summer resort in Upstate New York -- we had a resident bat that patrolled the theater whenever we ran a movie. He (or she) would fly over the heads of the guests and apparently did a pretty good job of ridding the place of insects. I must admit, however, that many of the guests would duck and cover when the bat first appeared. Guano aside, perhaps you need a flying patrol!

I also live on a farm in Ontario and was plagued by mosquito's. We couldn't figure out where they were coming from. We also had a wet basement, sump pit, etc and had a cistern in the basement as well. We had mosquitoes not only all summer, but all WINTER as well. We have recently bought a Konk automatic sprayer, which uses natural pyrethrin to kill insects. No more mosquitoes, flies, ants, etc anywhere on the first floor. We will get more and put them in the basement and attic. Then we should be bug-free... indoors. I know you said you don't do this sort of thing, but perhaps others who have the same issue don't mind using natural remedies to cure the ills.

Hi - This is my first time reading your blog and can't wait to read more! We live on a horse boarding farm in Nova Scotia and we have mosquitoes in our house through the fall and early winter- long after the outdoor versions have disappeared. They are completely benign with only a few that flit around in various rooms not bugging anyone. By Valentine's Day they are all gone. I have no idea where they come from. They last way too long to be hold overs and they don't bite so they can't be surviving individually for the months that they continue to appear. We also have large numbers of lady bugs and houseflies all year long. The ladybugs don't bother me, but the houseflies are like a low grade headache that never goes away.

Hi,Your plague of mosquitoes sounds truly awful! We have a similiar influx of ladybugs, but they are no bother :) you mentioned seeing mosquito larvae in your rain barrels -- I was wondering if they are somehow hatching and getting into your house, perhaps through the gutter system? You could try the mosquito "donuts", specifically designed to prevent mosquito larvae from forming in ponds and standing water sources. I have seen them in several online catalogs, such as Gaiam and Real Goods. They might offer a non-toxic way to combat the little pests! Good luck!
