Yes you can kill Japanese Knotweed without employing a specialist, these are the main ways to get rid of it....
1, Using Glyphosate weed killers
This is the most effective way to kill and get rid of Japanese Knotweed I know and it is the method I use.
I apply it directly to the plant by painting it onto the leaves and the cut end of the stem, the glyphosate is taken in by the plant to the roots and kills the whole plant and root.
You can use the diluted branded glyphosate-based weedkillers like Scotts Roundup, Tree Stump & Rootkiller or Bayer Garden Super Strength weedkiller etc. Or do what I do and use the undiluted stuff available here. It is a lot cheaper and much more effective. Click on the add for more information

People who fail to control the spread of invasive non-native plants such as Japanese Knotweed could be fined or receive anti-social behavior orders
Japanese Knotweed growing in your garden, can potentially cause major problems, not only to your own garden and property, but to neighbours gardens and properties. I have listed a few tips and actions you should take to control the spread of Japanese knotweed.
The Wildlife and Countryside Act 1981 says, it is an offence to plant or grow Japanese knotweed where there is any risk of causing the plant to spread into the wild or neighbouring properties.
It also states that it is up to you the householder to control the plants from spreading. It is also illegal to dispose of Japanese Knotweed incorrectly, causing further spreading. I have included safe and legal ways of disposal on this page.
If you see Japanese knotweed growing in neighbouring gardens or on council property, try explaining to your neighbour, the potential damage to the countryside and property this will cause if left untreated. If reason fails or you spot Japanese Knotweed growing wild, the police have a wildlife liaison officer who can be contacted.

Finally a few precautions when dealing with an infestation of Japanese Knotweed.
People who fail to control the spread of invasive non-native plants such as Japanese Knotweed could be fined or receive anti-social behaviour orders (Asbos), the government says.
The weed is one of the most destructive plants in the UK.
The new rules mean people can now be fined up to £2,500 for failing to control it.
And companies who fall foul of the law can be fined up to £20,000.
The Home Office says these plants threaten the UK's biodiversity by crowding out native species and destabilising riverbanks. They can also do immense harm to forestry, farms, roads and buildings.
Japanese knotweed can grow through tarmac and cause structural damage to properties,
Japanese knotweed is particularly difficult to eradicate. It is very resilient and regrows vigorously after being cut down.
The most effective method of eradicating it is by using glyphosate in the late summer or autumn, when it is close to its flowering stage.
