Crows tearing up north Dartmouth lawns in search of food

Lawns in north-end Dartmouth are under attack by crowsripping up the grass to get at an infestation of beetle larvae, also known as grubs.

"It's a mess here," said Jim Dewolfe, who's lived on Moira Streetfor 40 years. "They've kind of taken over."

The first time he said he noticed the problem was in 2016, but a year later it'sworse.He has a bucket handy with pebbles that he throws at the crows to try to keep them at bay.

His problems come as another Nova Scotia community faces grub and bird issues. Middleton has been forced to close it municipally run sports fields because seagulls and other animals are tearing up the turf to get to the insects.

The only real solution is to try to reduce the what's attracting the birds. Grubs are short, fat worms, while another problem larvae called leatherjacketsare longer, skinnier and are black or brown, according to EmilyTregunno, a gardening expert atHalifax Seed.

In north Dartmouth it appears the white larvae are the problem.

There is only one approved treatment product available in Nova Scotia, according to Tregunno. It's called a nematode, which is amicroscopic wormthat eats specific insects from the inside out.

"So if you have a grub or a leatherjacket, you need a different species of nematode in order to control them," saidTregunno.

The cool spring weather is not helping the situation because nematodes cannot be spread on lawns until the temperature warms up.

It could be the end of May before the nematodes can be applied, and one application may not be enough.

"My neighbour bought it and right now it doesn't seem to be working," said DeWolfe."We're waiting for somebody to come up with anothersolution."
