There are two kinds of rat mites, the spiny rat mite and the tropical rat mite. Both reside in cracks and crevices that are close to rat nests, and while both prefer to feed off rats, they will feed off humans if the rats abandon their nest or die. When tropical rat mites bite humans it can cause skin irritation, itching and pain. Fortunately, there are methods for getting rid of rat mites.
Eliminate the Source
When you are dealing with rat mites, you are also dealing with rats and possibly other rodents in your home. One of the first things you need to do in order to eradicate rat mites is to eliminate the source: the rats. Either kill the rats with poison or trap them, but they have to be removed from the home. Once this is done, any remaining rat nests have to be removed from the home as well, because these are among the places rat mites congregate.
Plug Up Any Holes and Entries
Once the rat nests have been eliminated, it is important to go around the home and block up all potential entrances for rats and other animals, such as birds and other types of rodents. This includes mouse holes, openings on the outside of the home through which mice and other vermin could crawl into the home. Making sure the rats and other animals cannot get back in is crucial, because otherwise they will return and there will again be a rat mite problem.
A vacuum can be the most valuable weapon against rat mites, and in some cases has been able to completely eradicate rat mites from the home. Rat mites like to congregate in the cracks and crevices near rat nests, so vacuuming the home completely, including areas close to and around cracks and crevices, can in most cases get rid of all or most of the rat mites in a home.
When dealing with rat mites it's important to control the amount of moisture in the air. The best way to help eradicate rat mite populations and to keep them from becoming a problem is to keep the humidity in your home below 50 per cent. When the humidity rises higher, the homeowner can end up with an exploding rat mite population. One final thing to keep in mind is that low humidity in the home has to be maintained for several weeks in order to be effective.
