  We obtain explicit forms of the current best known asymptotic upper bounds
for gaps between squarefree integers. In particular we show, for any $x \ge 2$,
that every interval of the form $(x, x + 11x^{1/5}\log x]$ contains a
squarefree integer. The constant 11 can be improved further, if $x$ is assumed
to be larger than a (very) large constant.
