That’s a really weird reply.
I am definitely not against pest controllers or pest control. Some of my best friends are pest controllers of one sort or another

.
On squirrels. Until recently my roof was cedar shingles on a single storey house surrounded be by chestnut trees etc so I take steps to encourage squirrels not to trespass there and usually shoot them if they get numerous.
Ditto mice in the house which I have from time to time.
And you know I’ve had a constant war against rats when I had poultry, though nowadays I wouldn’t bother if I just saw evidence of a visitor — I don’t have any resident as the dog would tell me.
I am curious why you worry about ants in your lawn, since you’ve mentioned it more than once, as you don’t strike me as someone who has aims for a bowls green type lawn where ants (and worms!) might spoil the appearance. But I’m just interested and not trying to get at you! They can be a nuisance in the house and some can be serious pests there, like the fire ants — though I don’t think we have them here … yet — but I haven’t come across any that are a problem in gardens unless one is the kind of gardener that aims for everything “pristine”.
As for “following you around, it’s in WCMUT which I read from time to time.
