Preventing Outdoor Pests From Coming Indoors
Sealing your home.
It is a necessary fact of life. You have to breathe. Stop doing it for more than a couple of minutes, and you are a goner! Your home has to breathe too, and In order to breathe, in order to allow entry for pipes and cables, in order to vent heat and harmful gases, there have to be openings in a home. The primary openings are:
Power, communication, and transmission lines and pipes:
A home with out some forms of ventilation would soon destroy itself. A home without electricity, plumbing and communication would not be much fun!
So, how do we accommodate all these holes in our homes, and still keep little critters out? Well, that is what this is about.
How To Close The Border
Before central heat and air, there were devices in homes to allow for the adjustment of temperature through the use of ventilation. We still have them in most homes today where they often serve as nothing more than vestiges of the ancient past. These were known as windows. Often the doors were used for the same purpose in the summer.
How did they manage to open these ventilation devices without allowing bugs in? This was accomplished through window and door screens. Taking a lesson from the past, we might consider the use of screens over the vents. Most home builders now screen vents, but there is always a chance, and you should check yours. Sometimes some are omitted by accident. I have seen a number of cases where rodents gained entry through dryer vents, and then chewed through the vent hose to get to the cheese and crackers. Write yourself a note to periodically check these vent screens for clogging.
Other entry routes into the home, pipes and cables, will need to be sealed using another ancient technology: Caulk. A tube of high quality caulk is one of the best tools in home pest prevention. Seal around those entries on the outside of your home. Even the very small cracks and holes. You might be surprised just how small an insect or a rodent can become when it is hungry, thirsty, hot dry, wet or cold. When you are done with the outside of your home, you are not done!
On the inside of your house, you should do the same thing. Give special attention to plumbing drains. Very often a box was used to to form around the bathroom piping for the plumbers to make all the connections. If this area is not filled before the walls are completed, there will be exposed soil on the inside of the wall. Most pre-treatments for termites will lower the chances of anything coming into the home through these openings, but occasionally some do. If you have easy access to these areas through a pipe chase, filling the area with mortar or some other hardening substance is a good option, if not, the first time that a repair is made to your plumbing requiring a plumber to open up the wall, you might be able to do it. Otherwise, make sure that the inside wall is sealed well.
