Abstract: An animal and insect exterminator for burrowing-type animals and insects. The exterminator includes an elongated tubular member which is adapted to be inserted within an underground burrow or nest. A shatterable tip member is replaceably mounted on one end of the tubular member and includes an explosive charge, such as jellied methanol or black powder. A detonator is carried by the tubular member for detonating the explosive charge so as to shatter the tip member and propel fragments of the tip member throughout the underground burrow or nest. The detonator includes a primer which is mounted within the tip member in proximity with the explosive charge and a trigger which forceably engages the primer to detonate the primer.
