First of all, sorry for what is a post about getting rid of ants in a forum dedicated to keeping ants, but I figure this is where the knowledge resides. I am actually quite fond of ants, and have kept Lasius niger in the past - yet this time their presence is unwanted and I would very much appreciate advice on how to best make them leave my apartment for good.

 

Long story short, I moved into a new apartment in the middle of Berlin (Germany) last September. In spring I first noticed an ant-trail in my living room, running from under the wooden floorboards near my balcony door (2nd floor, so quite high off the ground in a 6-storey, 100 year old apartment building) to some uneaten pizza that was lying around (I have since stopped doing that). At the time it was enough to clean the room and lay out some ant traps - the ants mostly disappeared for the next few months. Early summer they came back though, but this time a borax-sugar combination I read about online was enough for them to again mostly disappear, with just a few wandering around now and then). Then a few days ago: nuptial flight. I had noticed an uptick in the amount of ants leading up to this, but the flight itself is ongoing (day 4) and pretty wild in the evening and night, the number of virgin queens flying around must be in the hundreds, not to mention a large number of males both flying and walking. 

 

I had pest-control come by the apartment yesterday daytime, when activity was very low. She squirted some gel (wish I could say which kind, not sure) near to where the ants are appearing from the floorboards, and told me to call again in 2-3 days to repeat the process if the ants were still there. It has only been 24 hours, but the ants are very much there - and I don't think the person I had over knew much about nuptial flight, its scale, or whether this had any impact on how she should be dealing with the situation.

 

My questions I guess are how to best deal with this situation, during flight, but also how to get rid of this colony over the long term. Having a huge nest underneath my floorboards is not really viable. 

 

I've attached some photos of the species in question. Many thanks for any help and guidance.

They look like Lasius emarginatus. I would suggest just not giving them a reason to come above the floor boards. Just do not leave food out and you should not see a lot of them. As for the nuptial flight, I do not know, they started flying in your apartment???

Thanks Gregory for identifying the species in question. I was able to read up on it some (http://www.ameisenwi...ius_emarginatus - link in German) and it seems they are known to nest in residential structures. For virgin queens to swarm indoors also seems normal, if there are indoor nest exits. And from what I can gather, I might have a very hard time getting rid of these guys, oh my ...

Well, you did come to the right place! :D I had a bad Argentine infestation and nothing really worked. I tried the different baits that were supposed to be slower working so they can feed it throughout the colony. The Combat Gel worked too fast (but it did work). What did the trick for me was the Hotshot baits. I also tried all those so called home remedies (aspartame, borax, etc.) and those were all a bust. You can also try diatomaceous earth, since you can probably get that through the floorboards. I also wonder if imidocloprid foam would work. It comes in a pressurized can to inject into the wall for termites. Worked great for me but I had to drill holes in the wall. Is there a crack or space you can maybe get the nozzle in?

 

Isn't Bugfinder in the killing business?


Camponotus vicinus, Crematogaster 1, Crematogaster 2, Formica francoeuri, *, *, Myrmecocystus testaceus, Novomessor cockerelli, Pheidole hyatti, Pogonomyrmex californicus, Pogonomyrmex rugosus, Solenopsis invicta

His is not in the ant killing business. He only kills bed bugs with his dog.


Species I keep:

 

1 Lasius cf. Neoniger 30 workers

1 Camponotus sp. 15 workers

20 Tetramorium SpE 30 workers

1 T. Sessile 200 workers

I don't know if you get it there. Might be illegal. In the U.S you can get this stuff called Amdro Ant Block. Comes in granules, and kills Argentine ants in a huge radious. I put some out last year, and a few days later, Argentine ants were completely gone. They've come back this year, though. last place I lived, we put some out, and never had an Argentine ant problem again for 2-3 years.

 

Its pretty poisonous, and animals tend to like to eat it cause its sweet tasting I guess. I've never seen dogs/birds eat it, but it is a warning on the container to keep away from pets and that birds might consume it.

 

Its only stuff we've used that works on Argentine ants, though. And works on pretty much every other ant. We tried TONS of different ant baits, and they were useless...including hotshot that was mentioned. Too many Argentine ants and the baits barely did anything. Ant Block worked 100%. And, spraying poison is a scam as that makes the Argentine ant queens produce even more ants, along with probably any other ant spraying is used on. Pest control do it so they can come back, cause if they got rid of the problem, they'd lose money. :P

 

One of my family members used it on Solenopsis invicta last year, he had over 1000 mounds on his property (its a pretty big property). He put Ant Block all around, a month later each and every single mound was empty and he even had native Pogonomyrmex rugosus (in Arizona) return to his property like they used to be years ago. Along with other native ants.

Hmmm... Well if they nest in structures that is them for sure as there are no other ants in Germany with that coloration.
