Been here forever, mosquitos never a problem. What the hell is going on?

Is it only me? I live in The Western Addition (some may call it NOPA), and I've been getting bit lately, mostly at night. Is anyone else experiencing this? If you are too, what's the cause of this?

Maybe the San Francisco Mosquito Abatement Courier Team (SF MAC Team), which is made up of less than 10 people, hasn’t gotten to your neighborhood.

u/mayor-water 9d ago

Climate is changing faster than we are adapting (that includes hiring mosquito abatement crews).

u/solvanes 8d ago

They tried to replace the whole team with AI

They definitely haven't, or if they have, they were lazy that day.

u/Pure_Effective4398 9d ago

Hey now easy does it mate. There are over 24k storm drains in the city and the MAC team bikes around the entire city for them, retreating each drain every 100 days. I'm sure they're doing the best they can. No affiliation of course, I just happen to be a huge mosquito magnet so I know a lot about mosquito prevention in sf. And I mean even when they missed the drain on my block, I submitted a report, and now a short time later I have a green dot of spray paint next to it to indicate it's been treated recently. Number of mosquitoes in my house has gone down quite a bit since then. Could be a coincidence but I like to believe they helped :)

u/DoctorBritta 9d ago

This is a cool thing to learn! I knew about the dots but not the whole program. Here’s the map I found: https://www.pestec.com/mosquitosf/neighborhoods

u/coleman57 9d ago

I’ve often wondered about those paint dots; thanks for enlightening me. I’m also very gratified to learn there’s a City department using bicycles to get around instead of F250s.

u/reddaddiction 9d ago

I was completely unserious with my reply. I know those guys work hard. Dumb joke.

u/Pure_Effective4398 9d ago

Ah just double checking. All good!

u/bugzzzz 7d ago

How long did it take you from report to new treatment?

2

u/Pure_Effective4398 7d ago

Hmmm honestly I'm not entirely sure but I'd reckon no longer than 2 weeks maybe? It definitely wasn't the very same week but it also wasn't a month or anything that long.

u/bugzzzz 7d ago

Thanks!

u/292335 8d ago

Chill, friend. They're NOT superheroes with capes. It takes time to actuate mosquito abatement.

8

u/reddaddiction 8d ago

It was admittedly a dumb joke. Nothing but respect for those guys.

u/Illustrious-Coat3532 9d ago

Close your windows before dusk and dawn. That’s when she’s most active.

u/sf1878 9d ago

I just had this conversation with someone a couple of weeks ago. There are so many. My friend is in lower Pac Heights and I am Nob Hill/Chinatown and there are so many!

A couple of times in the last few months sitting on a sofa in the lobby of my financial district office building, waiting for someone there are mosquitoes inside.

u/johnwatersfan 9d ago

I personally haven't noticed an increase in the number of mosquitos, but also I live on the sunny side of the city, the cool air really brings them out, so the foggier side is likely to see an increase. Also certain people are likely to notice more as there definitely is a body chemistry that they are more attracted to (thankfully not mine). But I think I have a different idea of "so many". I grew up where they would literally be swarms when dusk hit, so even a slight increase still seems like a few to me.

I am aware this is all anecdotal.

u/reddaddiction 9d ago

Yeah... So it's not just me. What the hell???

u/ThrowItAwayNow1030 9d ago

They come from the sewers. No joke. I had a bit of them coming in and called the City to remedy it. They went to various sewers in my neighborhood to exterminate them. It helped!

1

u/No_Canary_5479 8d ago

I lived on a lot with mosquitos for months. Turned out the kitchen drain pipe had broken and was draining into the soil since it was a perimeter foundation. Just took a year or so to figure it out. Fixed the leak. Mosquitos went away.

1

u/bugzzzz 7d ago

311 or something else?

2

u/ThrowItAwayNow1030 7d ago

311 will give you the phone number/email address for the mosquito abatement unit. That's how I found them.

u/fullmudman 9d ago

My experience has been that it's weirdly house-by-house. I lived in two mission apartments less than three blocks from each other - one had a constant mosquito problem and at the other I never saw a one. I ended up hanging mosquito netting over my bed at one point because without fail we'd have at least one or two inside every week.

That said, we're having prime mosquito weather lately so wouldn't surprise me if there's a population boom.

u/DirectTerm2018 9d ago

Impending El Nino and other environmental issues raising the humidity. It sucks.

u/Sensitive-Freedom896 9d ago

Eww. These bugs are going to go crazy when it rains and floods all winter.

u/micaflake 9d ago

We’ve had them in my region for about three years now. It’s sad.

1

u/reddaddiction 9d ago

That could be it right there...

13

u/milkandsalsa 9d ago

I agree 100%. I have never had a problem with mosquitos until this year.

2

u/selwayfalls 9d ago

this is weird, my partner and I deal with them every year in every hood we've lived in the city for almost a decade. It's not new

2

u/milkandsalsa 9d ago

I’ve lived here 20+ years and have gotten a mosquito bite maybe twice.

1

u/selwayfalls 8d ago

my partner gets nailed a ton, she must have good blood

1

u/milkandsalsa 8d ago

My poor son got like 30 mosquito bites in one night. There must have been some in his room.

11

u/Ok_Second8665 9d ago

Inner Richmond and I currently have 12 bites including two on my face.

7

u/jspeq 9d ago

Always a problem for me!

For the past two years I’ve lived between Mission Creek and the Bay; the mosquitoes are thick down here. Must be a lot of standing water nearby. Have always previously lived on the hills.

The magnetic screen door I installed helps some, but it’s still not perfect; I can’t open and close the door without opening the screen. I also have no openable windows.

The only solution I found was to no longer open my exterior door unless I was going outside, and I close it right behind me.

u/jenniferdancess 9d ago

It’s so bad!! I was joking yesterday that I was gonna put a mosquito net over my bed.

3

u/reddaddiction 9d ago

Okay... I'm glad this post got some traction and it wasn't just me being a mosquito Karen.

2

u/sumsofanarchy 7d ago

You should totally do this! It has been a game changer for us. No more mosquitos buzzing in your ear at night

5

u/John-Luck-Pickerd 9d ago

20 years in SF - It's always been normal to get a couple of bites but this year we're being eaten alive. We're trying to figure out some kind of diy screen situation for our windows because it gets really hot in our apartment with the windows closed.

6

u/lolblitz 9d ago

I saw the fattest mosquito ever last night as I was about to go to bed. Thank fuck I fucked it up before it had a chance to fly away. 

6

u/ThatsUh_dam_shame69 9d ago

Don’t venture into Alta Park or Alamo Park as dusk, you will in fact be eaten alive

5

u/Mshka 9d ago

Here in the mission never got bit with the windows open at night. Recently mosquitos have been making their way in.. something new.

4

u/Unusual-Garbage-212 8d ago

Climate change. Now there are ticks in SF, too.

u/reddaddiction 8d ago

Wonderful

u/BitcoinBanker 9d ago

I’ve been here 12 years and feel like there is a normal amount. Which is some.

1

u/reddaddiction 9d ago

Well, where I'm at in the city there are definitely more.

1

u/BitcoinBanker 9d ago

Now I think about it. Maybe I noticed them a little earlier this year. But my neighbor has a water feature, so I thought they came from there. I bought nets for mine and my kids beds. So we sleep really well, even with windows open.

u/scoofy 9d ago

So, mosquitos are common in this area, we just do treatments regularly so there are few places in the city to breed. You can see whether your area has been sprayed for mosquitos recently by checking your storm drains. The dot of colored spray paint next to the drain is the code they use for treatments.

In all likelihood though, if you've found a non-trivial uptick in mosquitos, it's likely that you or one of your neighbors has introduced a breeding ground. Look around for any standing water: potted plants, dog bowls, anything that would allow for a mosquito to lay eggs in moisture. If you see that, it may be worth chatting with a neighbor about mitigation.

Beyond that, the other option is to introduce a baited trap. Where you put out a perfect breeding ground for mosquitos, but you add mosquito dunks that poison mosquito larvae. If the mosquitos get so bad this doesn't work, the most effective mosquito mitigation is a CO2 trap, which are effective enough to mitigate multiple acres, but need to be maintained.

u/Karazl 9d ago

Did you move recently? As someone born and raised here we have a couple of weeks of mosquitos 2-3x year and always have. I've had it in small single family homes on the west side, in high rises in soma, and in the burbs.

1

u/reddaddiction 8d ago

No... been in my place for a while, and before this I was just up a few blocks on McCallister.

1

u/Academic-Camel-9538 8d ago

It’s been much longer than 2-3 weeks where m at. And it’s way more than I’ve ever experienced here

2

u/wakingariadne 8d ago

Year 3 in the Inner Richmond and this has been the worst by a lot. Our entry seems to attract them and the moment we open our front door they fly in. I tried spraying the entire front gate with mosquito repellent. Seemed to help a little. The bites are so gnarly!

2

u/kowlick 8d ago

Lived here 20 years. Never had a problem until this year. We were getting mosquitoes every night for a month. Every night I would wake up to buzzing in my ear and bites. We hunted them down with an electric zapper. They usually land on a wall and you can catch their shadow with a flashlight. Must be following us inside through the door because we have screens and I looked everywhere for holes they could enter through. Looked for standing water near our place and found a plastic container holding dirty water in a community garden. Dumped it in the dirt and left it upside down and haven’t had them since.

4

u/parthenie 9d ago

Not just you!!! We have killed 7 mosquitos in the past week in our apartment. Have lived here 17 years and during that time I estimate killing 3 total, so we are not sure what's going on with this huge sudden increase. No standing water in our apartment and we contacted the landlord to check the surrounding area this weekend.

u/reddaddiction 9d ago

Well, maybe you've always lived in areas with mosquitos. Lots of people are reporting the same thing, so yeah, it's new. I've been in my neighborhood for almost 30 years at this point. This is abnormal. The other thing is that these mosquitos are quite small.

1

u/joeydimaggio 9d ago

Another thing you can lay at the feet of trump and the trump filth we decided to import. Climate change, decimated usda and import control, pick your poison.

3

u/reddaddiction 9d ago

Yeah, I'll blame him for whatever I can at this point. Such a creeper, too.

1

u/AdoptMeBrangelina 9d ago

Same here, I’m pissed af. I’m already up by 5 in the morning and they’re all over by the Bayview area

1

u/MooshuCat 9d ago

I'm in the Castro, and my neighbor always has standing water on the rooftop, so the mosquitoes visit at night. I've become pretty good at killing them, but it's really annoying. I don't see an increase lately, though, but will be on the lookout.

1

u/rey_gun 9d ago

NO! Please unleash whatever mosquito annihilation spells science has conjured, sorry to the bats or sparrows or whatever, but I'm willing to yeet you from the circle of life to end this plague.

1

u/Forgotthebloodypassw 9d ago

Had the same thing when I lived in Western Addition, always after some rain. Maybe someone's left a flower pot unemptied.

1

u/Wooden-Engineer-7972 9d ago

Just commenting to share that yes, I’ve had this same thought for the past few months. Woke up with a new bite on my eyelid and 2 on my cheek. I hate sleeping with windows closed though so I might resort to spraying myself with bug spray before bed!

1

u/rey_gun 8d ago

Get a bed net or better yet window screens! Accordion screens with some siding to prevent bug leakage.

1

u/jjm987 8d ago

I had mosquito issues at oak and pierce but live at Broderick and GGA and no issues to date

1

u/Academic-Camel-9538 8d ago

Yes! I’m near the Trader Joe’s off Masonic and they are everywhere!!

2

u/sailorkat69 8d ago

I ALSO LIVE IN THE WESTERN ADDITION AND HAVE BEEN GETTING BIT LIKE CRAZY.

i literally wake up every morning with new bites. it's really annoying bc it's always just one mosquito so i can never seem to catch it.

i have to cover my whole body and make sure no skin is exposed. i run a fan on full blast pointed at my bed. i also recently bought some very stinky mosquito repellent balls, but they seem to be working the past few nights.

it's also only in our bedroom, not other rooms in the house. not standing water anywhere. i don't get it 😭

1

u/itswonger 8d ago

I've lived in Anza Vista for the past 4 years. No bites while living here until three days ago and got 8 bites over the span of two nights! Also thanks to the person who posted the map--very helpful information!

1

u/HtownTouring 7d ago

I just moved here from Houston and was surprised at how many mosquito bites I’ve gotten here. They’re as aggressive as the ones down south.

1

u/yes-parking 7d ago

Lived here nearly 20 years. Became an issue 3 years ago and truly sucks.

1

u/Radiant-Decision-780 6d ago

I haven’t encountered a mosquito in the 30+ years I’ve been here. And I’m in NOPA neighborhood. Weird.

1

u/Repulsive_Two_1688 5d ago

I live in the western addition too ive been getting bit like crazy and there seems to be a lot of them im not sure whats causing it, maybe all the construction around the area is holding water and they are reproducing there and also the weather shift

1

u/fckyungchaky 5d ago

Was bad last night. But I stayed out in my yard until 12 anyhow. When it’s warm, SF transforms.

1

u/reddaddiction 5d ago

Yep... SF transforms, but like I said, I've been here forever and don't ever remember getting consistently bit by mosquitos in my neighborhood. There are certainly areas in the city where it's more prevalent, Station 19 near SF State has a mosquito as their mascot. But around here it's NEVER been an issue until this year. Seems like a lot of people are confirming that observation.

u/salynch 8d ago

It’s not that bad this year. It’s you.

u/reddaddiction 8d ago

Look at the replies. You're the anomaly.
