# Invasive Plants Increase Mosquito Populations in Baltimore and DC Mosquito-borne diseases are on the rise in low-income areas. - **Source:** [Phys.org - latest science and technology news stories](https://brifing.si/source/8b0f98da-d179-4c93-871f-7ac460bf9c61) - **Published:** 2026-07-21 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/d49c1c8f-2d46-4fbb-b733-eba9c0ced65d ## Mosquitoes and Income Inequality Mosquito populations are known to be higher in low-income neighborhoods, increasing vulnerability to mosquito-borne diseases. A new study by Cary Institute of Ecosystem Studies investigates the reasons behind this phenomenon. ## Role of Invasive Plants The research found that invasive plants are more common in low-income areas of Baltimore and Washington DC. These plants create ideal breeding grounds for mosquitoes, boosting their populations. ## Plant Species and Mosquitoes Invasive plants retain more water compared to native species, leading to the formation of stagnant water pools where mosquitoes can lay their larvae. ## Health Risks The increase in mosquito populations raises the risk of diseases like West Nile virus and Zika. This poses a serious threat, especially for residents of low-income areas. ## Environmental Factors The study highlights the impact of environmental factors on mosquito populations. Controlling invasive plants could be a crucial step in preventing mosquito-borne diseases. ## Measures and Solutions The research emphasizes the importance of local governments developing policies to control invasive plants. Such measures could reduce mosquito populations and protect public health. ## Sources covering this story - https://phys.org/news/2026-07-invasive-boost-mosquitoes-income-areas.html — --- _Summary written by Brifing from the original reporting.
