During a Commons debate this week Colvile called on ministers to urge housing developers to create specialist habitats for the animals when they build new homes - starting by leaving holes at the bottom of fences for them to crawl through.
"The government needs to make it as easy as possible for hedgehogs to move between gardens to get more room. The key to that, ideally, is to make a hole," Colvile told The Times.
He also called for hedgehogs to be given national status, with polling suggesting hedgehogs are the nation's favourite animals.
Colvile has previously had success campaigning for hedgehogs in Parliament. His latest effort led a Government minister to call for people to check their bonfires on Guy Fawkes Night to ensure there are no hedgehogs trapped inside.
There are thought to be fewer than 1m hedgehogs left in the UK.
