All you need for proper lawn and garden care are a round spade, a square spade, a metal rake, a lawn rake, a hand trowel, a good pair of work gloves, a lawnmower, a wheelbarrow, a sickle if you have long grass or brush to clear, and a powered roto-tiller if you want a sizable vegetable garden. And a beer. Teach you teenage children how to use each safely, then sit back and drink the beer. Ants are alien beings. I don't know who got out the scale and actually figured this, but think about it the next time you step on an ant that got into your kitchen because you dropped a cheese curl.
Ants can get through the tiniest hole or crack.
They can even get into a non-existent hole. This can only be proof that they traveled here a long time ago by alien spaceship and decided to take over our planet one ant hole at a time. Mulch is necessary for life. You may not have thought this before, but how do you explain the sudden appearance of mountains of red mulch, brown mulch, hickory mulch, pine mulch, mulch, mulch, mulch in the springtime. We never needed so much mulch before.
