All old tract houses have small eat in kitchens, outdated appliances, heating and air conditioning, etc.

You mix it in warm water & heat the treated area before & after application for temperatures below 45 degrees.

It worked.The killer would be forced air venting but we had steam heat.

Inspect the property for potential deferred maintenance or needed capital improvements (roof, heating system, etc.).

That's a big factor, especially somewhere with cold winters like PA, if the heat were paid by the landlord.

You could have electric heat, so no need to consider heating fuel unless you want to use some other fuel source.

ThanksTexas has an implied warranty of habitability that appears to mean a rental must be dry, heated, with flushing toilet, etc.

This means more frequent furnace filter changes and vacuuming of electric heating devices.
