urine-trouble

ughhhh everett peed in my house yesterday and I thought i fixed it when i treated the rug in the area he supposedly peed in and i let it air out a lot today while we were on our walk and it still smells like really strong pee

what do you guys do when youre not sure if youve found the entire source of urine smell? I cant figure out where it’s at at all, and I’ve sprayed the entire house with this pet odor killer & urine stain remover and I have hardwood floors so this is really difficult for me

I cant bear to have my house smell like urine. normal dog smell i can do. urine I can not.

help? :(
