It is possible to prevent spiderwebs from overtaking the outside of your house without power-washing or chemical insect repellants. All-natural sprays called "web repellants" use a combination of all-natural essential oils -- like thyme, lemongrass and citronella -- and liquid soap to make these areas of your home less attractive to spiders. The arachnids will avoid where you spray and set up their webs, which are effective to keep insects like mosquitoes at bay, elsewhere.

If you're wondering why your central air conditioning unit is keeping your home too cold in the warmer months, it may be what's affecting your programmable thermostat. If you keep heat-producing items like lamps, electronics and appliances near your thermostat, it can throw off the entire air conditioning system. It will read your home as much warmer than it actually is and force the system to work harder. Be sure to place your thermostat away from heat-producing items and out of the sun's rays.

Does your home have an attached, enclosed garage? You may want to reconsider parking your car inside. A study by Health Canada looked at the indoor air quality of 100 homes.

Because benzene is a toxic chemical that's related to gasoline. But if you want to park your car indoors, do this: Leave the garage door open for a few minutes after you get home. This will help flush out the toxic chemicals to keep your indoor air clean.
