My girlfriend moved in on Monday and found out that the apartment has a flea infestation the very next day.

They are horrible, crime infested areas.  

Here's what we operate by:Landlord Responsibilities: Landlord will at all times during the tenancy keep the premises fit for human habitation, and shall in particular:a.Cultivate, care for and mow surrounding grass, lawn, flowers, and shrubberyb.Maintain the premises to substantially comply with any applicable code, statue, ordinance, or regulation governing the premisec.Maintain the roof, floors, walls, chimneys, fireplaces, foundations, and all other structural components in reasonable good repair as to be usable and capable of resisting normal loadsd.Keep any shared or common areas reasonable clean, sanitary, and safe from defects increasing the hazards of fire or accidente.Provide a reasonable program for the control of infestation by insects, rodents, and other pests at move in f.Except where the condition is attributable to normal wear and tear, make repairs and arrangements necessary to put and keep the premises in as good condition as at move ing.Provide reasonably adequate locks and provide keys to the tenanth.Maintain all electrical, plumbing (main lines), heating, and other facilities and appliances supplied by Landlord in reasonably good working orderi.Maintain the unit in reasonably weather tight conditionj.Provide facilities adequate to supply heat and water and hot water as reasonably required by the tenant

Hard to assess that without knowing the scope of services you need and what the bid entails.We had a huge rat infestation problem at the primary home of my elderly mother.

Ants are part of life this time of year, and there isn't an infestation by any means (I worked in their house last week) and live next door.

https://www.ohiobar.org/forpublic/resources/lawfactspamphlets/pages/lawfactspamphlet-11.aspxObligation of landlord Maintain in good working condition all electrical, plumbing, sanitary, heating and air conditioning systems, and fixtures and appliances you have supplied.If you have notified your landlord, in writing, of problems at your rental property or of an insect or rodent infestation, the landlord should remedy the problems within a “reasonable” amount of time.

But essentially, your lease should state you are renting the lessee an apartment that is free of infestation and that any future infestation is the fault of the tenant.  

She lied to the judge and complained of ant infestation and raccoons in the house to buy more time as well. 

This is why I would NEVER own property in the liberal infested state of California. 

Apologies, I'm sure the topic makes your skin crawl but has anyone ever sold (or considered selling) due to a bed bug infestation?
