With recent changes to Pests by raxo2222 SVN 10381, it became imperative to go over and rework Pests.
Commit 10436 is the 1st set of changes to this group of trouble makers.
Players need to understand that Pests enter the game by Tech researched And by City size, ie Pop number.
Currently a City reaching size 4 has these 3 Pests (Ants, Fleas, Flies) that "May be introduced" once a City hits the set size. Techs are also involved in introduction of a pest. So are Terrain features (will be included later).
City size 4
Ants: Cooking, Preh Era Tech
Fleas: Canine Domestication, Preh Era
Flies: Scavenging, Preh Era
City size 6
Cockroaches: Sedentary Lifestyle, Ancient Era
Mosquitoes: Fishing, Preh Era
Ticks: Scavenging, Preh Era
City size 8
Lice: Poultry Domestication, Preh Era
Locust: Agriculture, Ancient Era
Rats: Sedentary Lifestyle
City size 10
Bedbugs: Sedentary Lifestyle
Termites: Simple Wood Working, Preh Era
Slugs: Plough, Ancient Era
City size 12
Aphids: Plough, Ancient Era
Crows: Sedentary Lifestyle, Ancient Era
Moths: Textile Loom, Ancient Era
Wasps: Apiculture, Ancient Era
City size 14
Gophers: Agriculture, Ancient Era
Pigeons: Civil Engineering, Classical Era
Raccoons: Civil Engineering, Classical
Seagulls: Sanitation, Classical
Most Pests are Obsoleted at Environmental Economics.
Those that do not are either replaced by a counter building (Replacement Building) or do not go away with obsolescence:
Ants: None
Aphids: LadyBugX ??? (part of Hydro's Insect farm chain iirc)
Bedbugs: None
Crows: Scarecrows
Rats: Rat Catcher
The Following give Disease/turn:
Bedbugs +1
Cockroaches +3
Crows +1
Fleas +3
Flies +3
Lice +1
Mosquitoes +3
Pigeons +1
Raccoons +1
Rats +3
Seagulls +1
Ticks +3
All give 1 Unhappiness
Almost all give -1
and 1 or 2 give +2 
Many decrease
by %
Some decrease
by %
Few decrease
or
by %
So here is your basic Overview of Pests in their Now current state. There will be some more changes. Also not mentioned is some depend upon Features to be present in the city's Fat X. I di not write them all down but will add these in to this post at a later date.
