How to Kill Moss on Pavers in Connecticut, Your Comprehensive Guide

In Connecticut, moss doesn’t just grow on patios; it moves like it owns the place. If left unchecked, your patio can become a hotbed for these squishy plants. Whether you prefer all-natural options or you’re a power tool aficionado, this guide shares tips showing you how to kill moss on pavers. 




There’s no need for harsh chemicals and gas-burning tools when the DIY options can be equally effective! Mix a 1:1 ratio of white vinegar and water in a spray bottle, and apply it liberally to the moss patches. The process is slow and steady, but eventually the moss dies, making it easier to scrape. 

  • Ingredients are easily accessible
  • White vinegar won’t stain the pavers if washed away and diluted
  • The method is only convenient for small areas
  • The solution will not prevent regrowth
  • There’s a chance that the vinegar can harm nearby plants if left to soak

Although it’s not the easiest method, it’s hard to deny how far a stiff brush and manual labor can get you. Scraping and pulling away moss is a straightforward and quick process. Using different tools, like a flathead screwdriver, allows you to clean tricky areas like joints and deeper crevices. 

  • Great for small areas that need an instant clean-up 
  • No sprays or chemicals required
  • The use of tools runs the risk of scratching pavers 
  • Most labor-intensive option by far
  • It can be a pain for large areas 

In our own business, a pressure washer is the go-to tool for moss removal, but a little finesse is key. It can be satisfying to blast moss and other debris away quickly. Still, you also run the risk of destroying paver joints. Anywhere from 1,200 to 1,500 psi is more than enough to dislodge stubborn moss. 

  • Quick and efficient, you can also polish pavers while you’re at it
  • Very effective for cleaning large areas
  • May require resanding of the joints afterwards
  • High psi washers run the risk of damaging pavers

If you’re not opposed to dousing moss in harsh chemicals, you’re in luck because the solution is simple! Diluting bleach in water and spraying it over the plant will cause it to wither and die in about 30 minutes. At that point, it’s easy to gently scrape then sweep away. 

  • Makes quick work of moss without long wait times and mess
  • Most homes have a bottle of bleach, making it very accessible
  • Be careful not to get the bleach solution on yourself or the surrounding plants
  • If left unwashed, it could stain pavers

Cut out the loud tools and science experiments, and use boiling water! It may sound simple, but it’s very effective. Most plants can’t bear extreme heat, so pouring a pot of boiling water on moss is a sure-fire way to kill it. 

  • Hands-down the most straightforward method
  • It can penetrate the roots, allowing you to remove the whole plant
  • Be cautious when pouring to avoid scalding yourself
  • Unless you’re boiling water in a 20-gallon bucket, it’s only effective in small areas

Moss thrives in low-light, damp environments. If the option is available, trim overhanging branches to allow more direct sunlight. 


Releveling your patio and considering French drains keeps moisture off the surface of your patio. By redirecting water, you minimize pooling, which can become a breeding ground for moss patches. 


Occasionally sweeping the patio surface keeps it free of debris, such as leaves and dirt. This debris can create a dense, nutrient-rich layer that is prime for moss growth. 


Sealers lock moisture out of your pavers, although it’s completely optional, it is a good long-term solution for preventing moss growth. Although it can be a DIY project, always do research before attempting it yourself. 



If you don’t want to worry about moss, having a professionally installed paver patio is the best thing you can do. If you find yourself slipping on these common plants, any of the methods listed here can be effective. Learning how to kill moss on pavers is easy. Just choose what works best for you!
