Flies - we've seen them hovering over refuse.

Mosquitoes The Size of Buicks !!!! ( Old Woody Allen Joke Actually About Spiders ) :
Not everywhere in Rapture is too cold ...
* Some of those old underground farms were pretty warm and humid...
* Some were located closer to the geothermal areas so they required less environmental control heating.
* Some mosquitoes breed in stagnant salt water ( perfect for leaky Rapture ).
* How much DDT is stockpiled somewhere in the City ???

Termites in Rapture ?? :
Alot of wood was brought in for Rapture's construction ( obvious there is alot of it behind the walls from all those damaged sections we've seen ) and there is alot of decorative woodwork ( and wood furniture, and crates, etc ... )
* The issue probably was not 'forgotten' when Rapture was being built, and large amounts of DDT and other treatments were used to process the lumber brought into Rapture.
* But all that smuggled material ( boxes and crates, etc ... ) could have been a new source and the smugglers likely didn't care a bit or take any preventative measures ( most of the crates left in the Smugglers Hideout would be sawdust by now ).
* Imagine what ADAM enhanced termites might do ( dosed via eating wood on the FrankenTrees ... )

Cats to Catch the Rats : 
Rats would have got to Rapture the same way as termites.
Even with countermeasures like fumigating of official cargoes bound for Rapture, smugglers didn't usually follow similar vermin control measures, resulting of unintended introduction of many unwanted visitors. Come to think of it, some of the criminal groups could have brought in 'human vermin' to reinforce their operations.

 "Blowtorch Used To Kill Spiders Burns Down Home" (Recent real world news story) :
So what's the spider situation in Rapture ?? You need enough prey for them to exist. We did see flies over rotting food (though for some reason the corpses remained maggot free).
Probably more commonly seen in the remaining active agricultural areas ( where lots of bugs they eat likely are ).
Note the Aviary (Bee place in BS2) - in Farmers Market, doesn't make that much sense unless linked closely to all the plants the bees get their sustenance from (flowers). You CAN feed them artificially, but that results in rather expensive tasteless honey. Much agriculture STILL has a dependency on Bee activity (fruit trees in particular ).

There would be other Sea Slugs brought in which weren't of the ADAM producing type.
With their simpler physiology, they were used for McClendon's Nerve Tissue experiments and developments leading to the Bio-Electronics technology.
