How to Prevent Mosquito Breeding using the B.L.O.C.K. Method

Mosquitos breed in water, including any water containers such as storage tanks, flower pots, discarded cups and bottles, and other areas where water is stagnant. Take action by removing stagnant water at your own home using the BLOCK method. 1. B- Break up hardened soil.


B - Break up hardened soil

Small pockets of water in hardened soil can serve as breeding sites. To prevent this, break up any compacted or hardened soil around your property, as it can trap water and create perfect conditions for mosquito larvae to thrive. Regularly aerating the soil can help prevent these small pockets of water from forming.


L - Lift and empty flowerpot plates

Flowerpot plates or saucers are common breeding sites for mosquitoes because they can collect rainwater or irrigation runoff. To prevent mosquito breeding in these areas, regularly lift and empty the plates to ensure there is no standing water. Additionally, consider using potting mixtures that drain water effectively and avoid overwatering your plants.


O - Overturn pails and wipe their rims

Containers such as pails, buckets, or even discarded tires can collect rainwater and provide ideal breeding sites for mosquitoes. To prevent this, make it a habit to overturn these containers when they're not in use. Also, wipe their rims to remove any residual water. Ensuring these containers remain dry is an effective way to eliminate mosquito breeding habitats.


C - Change water in vases

Flower vases often contain stagnant water. To prevent mosquito breeding in vases, change the water at least once a week to ensure that mosquito larvae do not have the opportunity to develop. Additionally, cleaning the vase can help remove any eggs or larvae stuck to the sides.


K - Keep roof gutters clear

Roof gutters can collect rainwater and debris, providing a perfect breeding ground for mosquitoes. Regularly inspect and clean your roof gutters to ensure they are free of obstructions and that water can flow freely. This will not only prevent mosquito breeding but also help maintain the integrity of your roofing system.
