Pet Odor Carpet Cleaner: 1 quart warm water, 1/4 C hydrogen Peroxide, 1/4 C distilled vinegar, 2 Tbsp baking soda, 1/2 tsp liquid dish soap. Spray on spot and let soak up to 30 minutes (test on carpet first, peroxide could fade carpet). Soak up as much of the liquid as possible and use a light colored towel and iron the spot out (this will pull the rest of the moisture and stain out)!
Keep this in mind if you start seeing lots of spiders around your place. Natural spider killer or preventer... take one cup of vingar, one cup of pepper, a teaspoon of oil and liquid soap. Put it into a spray bottle and spray along the outside of your outside door and along windows
