Top 5 things you need to know about the plant that's 'screaming for help' as it takes over entire neighborhoods
1. A single invasive species, the Japanese knotweed, has been found to grow through concrete foundations and asphalt driveways, costing homeowners thousands in property damage repairs.
2. Scientists have discovered that the plant releases a chemical signal when cut or disturbed, essentially 'screaming' to warn nearby plants and attract insects for protection.
3. Property values near a confirmed infestation can drop by up to 10-15%, making it one of the most financially devastating invasive species for homeowners.
4. The roots can burrow more than 6 feet deep and 20 feet horizontally, making complete removal nearly impossible without professional excavation and herbicide treatment.
5. Several states have now created 'knotweed task forces' and offer financial assistance to homeowners, as the invasive species is now reported in every US state except Alaska and Hawaii.
