My house is infested with rats.

Мой дом наводнял крысаы.

мой- nominative possessive pronoun.

дом - nominative noun.

наводнял - imperfective past; infested with rats in the past and still infested to present.

крысаы - (I am not sure of this; this might be irregular but it is animate accusative plural according to the table)
