Horse Apples and Longhorns

I have adorned our camphouse stoop with a galvanized bucket of bright green and bumpy horse apples and a Texas Longhorn cow skull and horns.   Horse apples aren't for eatin'.  For horses only.  They are the fruit of the bois d'arc tree which we have several of in the pasture and therefore apples aplenty.  I heard that if you cut them and place them in your home they act as an insect deterrent.  I tried it.  The ANtS came. Read they can be dried and used as ornaments.  Maybe next year.  But,they are beautiful to behold.  http://www.dirtdoctor.com/Bois-d-arc-fruit-Horse-Apples_vq364.htm
