A drip-feed container that holds pesticide or fertilizer on lawnmowers
It’d spread the liquid over the lawn while you’re mowing it. Kill two birds with one stone. Kill the worms and grubs, not the birds – actually, it would kill the birds if it destroyed their source of food. Forget it. heh.



I found this, but it’s for solid fertilizers.
Nice idea, as far as I can tell you can only get a huge thing for ride-on mowers, a simple drip feed would do it.
