Mosquito Trap Lid Stand Offs

5-Gallon Bucket Mosquito Trap Lid Spacer

Keep your DIY mosquito larvae trap protected from rain without cutting dowels or wrestling with zip ties. This 3D-printed spacer frame sits on the rim of a standard 5-gallon bucket and elevates the lid, allowing airflow while blocking rain from diluting your solution.

The trap concept: Fill a 5-gallon bucket with water and Mosquito Bits or Dunks (BTI — kills larvae, safe for bees, pets, and wildlife). Mosquitoes are attracted to standing water, lay their eggs, and the larvae die before hatching. No chemicals, no spraying. See it in action:

• Silver Cymbal – Mosquito Spraying is Expensive. Do This Instead!

• Arrow Pest Service – KILL EVERY Mosquito. SAFE For Honey Bees & Pets!

Why print this? Most builds use wooden dowels or PVC screwed through the bucket — functional but fiddly. This drop-in frame assembles in minutes with just three screws and keeps the lid elevated reliably all season.

Currently support two bucket options

• Home Depot 5-Gallon Orange Homer Bucket (#05GLHD2) + Homer Bucket Lid (RG5503) — ~$5.78 for the combo

What else you need:

• Matching snap lid for your bucket

• Mosquito Bits or Dunks (BTI-based larvicide)

Placement tips:

• Place in shaded areas away from direct sun — shade keeps water cooler and more attractive to egg-laying mosquitoes, and slows evaporation

• Position away from patios, seating areas, and high-foot-traffic zones — you're attracting mosquitoes, so keep them away from people

• Near tree lines, fence lines, or garden edges works well

• Multiple buckets = better coverage for larger yards

Print settings:

• Material: PETG or ASA recommended for outdoor UV/heat resistance

• 3 walls

• 15% infill

• No supports needed
