Not always is the answer, unfortunately many of the products sold for household use by untrained professionals may not get rid of all the fleas in your home. If some fleas are left they will reproduce and you will end up with a flea infestation again.
Boscastle
Boscastle is a village and fishing port on the north coastline of Cornwall, England, UK, in the civil parish of Forrabury as well as Minster (where the 2011 Census population was consisted of). It is 14 miles (23 kilometres) south of Bude as well as 5 miles (8 km) northeast of Tintagel. The harbour is a natural inlet shielded by 2 rock harbour walls integrated in 1584 by Sir Richard Grenville and is the only substantial harbour for 20 miles (32 kilometres) along the coast. The village extends up the valleys of the River Valency and River Jordan. Heavy rainfall on 16 August 2004 caused considerable damage to the village. Boscastle lies within the Cornwall Area of Outstanding Natural Beauty (AONB). The South West Coast Path passes through the village. The village, with its attractive harbour, is a prominent tourist destination. Amongst the attractions are the Museum of Witchcraft, Uncle Paul's Emporium, the Boscastle ceramic shop, and accessibility to the South West Coast Path. Much of the land in and around Boscastle is had by the National Trust, consisting of both sides of the harbour, Forrabury Stitches, high above the Boscastle and also split into ancient "stitchmeal" growing stories, and big locations of the Valency Valley, understood for its connections to Thomas Hardy. The previous harbour stables (part of the National Trust estate) are now a youth hostel run by YHA, popular with pedestrians. The National Trust runs a shop at the harbour, and also a visitor centre in the Old Smithy.
