Residents of a community in South Vancouver were fed. -
In addition to the sticky smells dripping from trees on the streets, some people are very annoyed that the city has not solved the problem.
Staff say they are doing everything they can to fight the root causes of the chaos, but it is a failed battle and they may not win if trees are not cut down.
To understand this, Joe Cole described the odor of dripping matter: "rotten garbage, rotten wine, honey and an impure mixture of semen.
"The problem stems from Linden Tree-
Or, more specifically, aphids attracted to them.
In summer, these aphids secrete honeydew. -a sugary sap —
The Park Board said they were foraging and breeding on the Linden tree.
It's very thick, with cars, roads, lawns and sidewalks underneath.
"It squeaks under a person's feet and attracts wasps. On 46th Avenue near Fraser Street, it falls so heavily that you can see it dripping in the sun," Cole said.
The problem lasts for months at a time, and although it's not the worst thing, it's "a huge inconvenience," Cole said.
He said, "Sometimes it drips on you when you get out of the car. You take the dog out for a walk. When they come in, you see their paws. It's stuck. "
"It's really disgusting.
"Cole asked City officials to do something. -
Spraying trees with insecticides releases a large number of ladybugs or thin plants, and replacing some trees with other varieties to reduce their attraction to aphids.
To be fair, as Amit Gandha, an urban dendrologist, explains, this is almost what cities have been doing.
The staff first counted the aphids on the leaves to determine whether the trees in a given block were infected with aphids.
If so, the block will be sprayed with insecticidal soap.
By the way, coll's block is on that timetable, and gandha recognizes its name.
Sprays clog pests and reduce their populations, but the problem is that aphids often breed. "When you do that, there's more," Gandha said.
Another control method is to release "biology". -
Controller"simply refers to predatory insects.
The city has also tried.
"Some of the things we don't release are wasps, because it starts with other problems, such as public safety.
But ladybugs, we've used them many times.
They don't seem to be able to keep up.
"Employees have another option when they do their best. -
Get rid of the tree.
According to the Park Council, in the 1980s and 1990s, Vancouver planted nearly 10,000 Bodhi trees.
Since then, about 1200 cars have been replaced, according to the board.
Gandiha explained that greater dialogue was needed between employees and neighbors before replacing the Bodhisattva tree.
Cole wasn't the only one on the street looking for problems with sticky trees.
Kenma, a nearby resident, said he would not park outside his house in hot weather when the trees were dripping.
If he did, he would have to wash his car every day.
Mahjong has lived in the street for decades. -
Like many of his neighbors-
He recalled that the big Bodhi tree planted in front of his house was planted more than 20 years ago.
"They're crazy," he said, noting that the branches were hanging low on the sidewalk, and the density of the leaves was enough to block the view of the nearby street lights.
Ma Ying-jeou said he would like to see cherry trees replace cherry trees in many streets of the city.
Across the road, Jim Ekin, the horse's neighbor, was loading his car.
He stopped in an ideal place. -
Under all kinds of trees, aphids are not attracted.
He said he liked the Bodhi tree, but he didn't like sticky things.
When asked if he would like the trees to disappear, he said it would be better to have something uninfected, but he didn't really think they should "clean up the neighborhood".
"For anyone interested in addressing aphids themselves, former Vancouver Sun Horticulture columnist Steve Whistler has two suggestions: hit them with a lot of water, or try to attract predators such as ladybugs, lace wings, aphid parasites and aphid dwarfs.
