Infection is common. Mortality has been reported mainly in juveniles and in association with other diseases. Deaths may be related to asphyxiation, excessive bleeding, or brain damage when leeches move into air spaces in the skull.

1 For instance, Fixr.com gives an overview of attic insulation costs, which can amount between $400 and $1,800 for the average home. 2  In general, the whole attic insulation will cost between $1.50 and $3.50 per square foot.
Add attic insulation to lower heating and cooling costs by as much as $600 per year. Save about $600/year by boosting the amount of attic insulation from R-11 to R-49. Depending on the type of materials you use, figure on paying an insulation contractor about $1,500 to insulate an 800-square-foot attic, which pays back your investment in three years. Youâll spend about half that to do the job yourself.
