Do holly bushes attract mosquitoes
Someone told me the holly attracts mosquitoes

It isn't that the bush, itself, attracts them because it is a Holly, rather the more compact it is the more it will attract them.
Some Hollies are very compact, which will hold moisture. This is a good breeding ground for mosquitoes. Other Hollies that are less dense will not have the same effect. This goes for most shrubs.
