The Mosquito Bucket Challenge 
Join thousands reducing mosquitoes without fogging—in your own yard.
A project by Homegrown National Park
How it works
Mosquitoes lay eggs in standing water. A mosquito bucket attracts them as a place to reproduce.
A mosquito dunk (Bti) prevents larvae from developing into adult mosquitoes, interrupting the life cycle and reducing mosquito populations over time.
What you'll need
- A bucket (5-gallon or similar)
- Water
- Organic material (leaves, grass clippings, or similar)
- A mosquito dunk (Bti)
How-To with Lid/Wire Cover
Set up your bucket
Step 1 - Decorate (Optional)
Decorate your bucket or use our ready-made sticker:
Step 2 - Add Water
Fill the bucket about two-thirds full with water.
Step 3 - Add Organic Matter
Add a small handful of dead leaves or grass clippings. As the water sits, it will begin to break down and become more attractive to mosquitoes looking for a place to lay eggs.
Step 4 - Add Your Dunk
Break up your mosquito dunk and drop approximately one-quarter of the dunk into your bucket.
Step 5 - Add Cover Or Stick
Add a lid with plenty of large holes drilled or wire secured with a rock or zip ties. Alternatively, (if you don't have pets or small kids), place a stick in the bucket so it leans out above the rim. This gives small animals an escape route if they fall in.
Step 6 - Place Your Bucket
Choose a shaded, low-traffic area where mosquitoes are likely to gather. Corners of your yard or along property lines often work well. (additional tips below)
Step 7 - Show It Off
Post your bucket on social media using the hashtag #MosquitoBucketChallenge. Find graphics and tools on the Share page.

How-To with "Rescue Stick"
Ways to improve results
- Start early in the mosquito season, before populations build.
- Use multiple buckets if you have a larger yard or multiple mosquito-prone areas.
- You can speed up the process by letting the water sit in the sun for a few days before placing your bucket.
- Drill a small hole at your desired water line so excess rain can drain and prevent overflow.
Where to place your bucket
- In shaded areas
- Near where mosquitoes are active
- Away from high-traffic areas
Buckets work best in quiet, shaded areas where mosquitoes are likely to gather. Corners of your yard or along property lines often work well. Try a spot that stays damp and undisturbed.
Safety and maintenance
Safety
- Use a cover, mesh, or safety stick to prevent access by children, pets, or small animals.
- Place buckets out of reach and check them regularly.
Maintenance
- Check water levels regularly.
- Replace the mosquito dunk about once a month.
- Without maintenance, buckets can become breeding sites instead of preventing them.
Additional best practices
- Dump standing water regularly—birdbaths, containers, and anything that collects rain are prime mosquito breeding spots.
- Plant native to attract birds, bats, and dragonflies, natural mosquito predators.
- Use repellents for personal protection rather than fogging your whole yard.
- These steps, paired with mosquito buckets, can reduce mosquitoes while avoiding broader harm.
