What's the PIE for louse's egg, nit?
 
Latin lens
Latvian gni~da
Lithuanuan glinda
Irish sned, gnit
Welsh nedd
Grk konis "dust"
OE hnitu = OHG hniz < PGerm *hnito:
Albanian theni
Armenian anic
Russian gnida (Other Slavic equivalents?)
 
It seems to exist a lot of corrupted variations of the same base.
I'd try to explain Latin as
 
*gnNd- (or knNd-) > gnend- > nend-> dissimilation > lend-. PIE *gnNd- (or knNd-) can explain Latvian, Lithuanina (dissimilated)
 Other words point to a *gnid-.
Greek, Germanic and Albanian point to a *k^nid-.
