Despite the fact I am against you trying to get rid of them (they’re cute!) I can give you a few helpful hints. Make sure that any cracks on the exterior of your house are filled in. That means getting out the good old caulking gun and going to town. Also, ensuring that all of your screens are in good condition and covering the appropriate areas will go far in making the inside of your home bug-free. If you’re that much of a fanatic, you can also make modifications to the outside of your house in terms of its color. Apparently if your house is a darker color, the beetles are going to be less likely to visit it. It’s important to keep in mind that the beetles are actually beneficial and are quite harmless. If they aren’t causing too much of a problem, leaving them alone isn’t a bad thing. Just a suggestion!
