In July 2009 I purchased a ‘modern’ log home (constructed 20 years ago – not an old, restored structure). As you can imagine there are (were) hundreds of crevices beckoning to every bat in the area as a roosting place. At one spot, where a dormer roof met the main roof, there was an opening where I counted approximately 100 small brown bats leaving one evening. These little critters were spending their days in the area between the roof rafters of that dormer. Late last fall I pulled the fascia, cleaned the excrement and plugged that entrance but am still suffering from the odors they left behind. And there were others placed I also ‘plugged’, that still have lingering odors.
What do you suggest?
At this point I suggest you do a good treatment with our NNZ or N7C odor neutralizer. It’s very effective at eliminating odors because it essentially “eats” them and breaks them down opposed to most agents which merely cover or mask the odor. As explained in our ODOR CONTROL ARTICLE, the big problem with most odors is that they’re essentially alive. This is very true with odors associated with animals and their bodily fluids. In this case no doubt the bat guano is involved and if you are to successfully eliminate the odor that shows up from time to time, you’ll need to distribute one of the aforementioned agents where the odor currently resides.
To do this you may be able to spray with a standard PUMP SPRAYER. But this could be a bit messy given where you need to treat. In the end you might find misting with one of our foggers will be easier to do. These tools are especially handy when one needs to spray open voids like attics and ceiling spaces under the roof. A fogger like our FM5330 or our FM6309 will do the job quickly and effectively. These units feature a dual benefit in that you can easily regulate the spray being applied to prevent over application which can happen when using a pump sprayer. When liquid spraying, the net result of over applying is a big “run off” mess. The second benefit using the mist is that it does a great job of filling all the gaps and spaces where odors might be hiding. This insures you don’t miss any key locations and in most cases you’ll achieve better results.
