fumigate ASAP or they will turn your house into an egg shell.my old house was completely infested with them.i would wake up everynight with termite waste(sand shit)all over my face in my eyes and all over the bed .they ate thru my books and also bite. within a year your whole house can turn into a giant nest.the sooner you exterminate them the better.if you dont do shit you might as well knock down and rebuild the home
