If you’ve noticed your home smelling stronger during warm days in West Covina, Covina, San Dimas, or anywhere in the San Gabriel Valley, you’re not imagining it—pet odors really do get worse when the weather heats up.
Even well-trained pets, clean homes, and regularly vacuumed carpets can start releasing odors once Southern California’s warm weather arrives. Luckily, there are clear reasons behind this and fast ways to fix the problem.
Below, we explain why heat intensifies pet odors, how to tell if the problem is deeper than the surface, and how to eliminate the smell quickly using the right professional treatments.

1. Heat Reactivates Old Pet Urine Crystals
Pet urine doesn’t stay liquid—once it dries, it forms urine crystals. These crystals remain hidden deep in your carpet fibers and padding. When the weather warms up, these crystals begin to break down and release ammonia-like odors back into your home.
That is why you may smell urine even if the accident happened weeks or months ago.
Warm weather = reactivated odor.
Surface cleaning or store-bought carpet sprays usually aren’t enough to dissolve these crystals. You need professional enzymatic treatment to neutralize them completely.

2. Humidity Makes Odors Rise From Carpet Padding
Even though Southern California is not known for heavy humidity, warmer months still increase moisture in the air—especially when:
- Running the AC
- After cleaning carpets without proper drying
- Leaving windows open on warm days
Carpet padding absorbs this moisture, which then mixes with old urine or bacteria and releases odor back into your living space.
If the smell gets stronger after mopping, steaming, or using a home carpet cleaner, it’s a sign the odor is coming from the padding—not the surface.
3. Bacteria Multiply Faster in Warm Temperatures
Pet urine contains natural bacteria, and warm weather speeds up bacterial growth. As bacteria multiply, they create stronger, more noticeable odors.
You may notice:
- Smells increasing in the afternoon
- Odors strongest near carpeted areas
- Persistent pet smells even after vacuuming
Only professional-grade hot water extraction and enzyme treatments can remove the bacteria and stop the smell at the source.

4. DIY Cleaners Often Make Pet Odor Worse
Many homeowners unknowingly worsen pet odors by using:
- Store-bought sprays
- Foam cleaners
- Homemade vinegar mixes
- Rented carpet cleaners
These products often leave behind soap residue that traps dirt and bacteria, causing odors to worsen as temperatures climb.
Some cleaners also push moisture deeper into the carpet, which activates the urine crystals and makes the smell stronger.
If you’ve cleaned an area repeatedly and it keeps smelling bad in warm weather, you need professional treatment.
5. Your Pet May Be Re-Marking Areas You Can’t See
Pets smell far better than humans. Even if you think you’ve cleaned an accident thoroughly, your pet may still detect it—and continue returning to the same spot.
This can result in multiple layers of urine deep in the carpet, often invisible to the eye but very noticeable when temperatures rise.
Our team uses UV blacklight detection to find every hidden spot before treating the carpet.
