Bugs in a garbage disposal are a common frustration in American kitchens. A couple of simple, step-by-step actions can stop infestations and keep the unit running smoothly. This guide covers practical, quick fixes and safe maintenance routines that homeowners can perform without specialized equipment.
Whether the issue is larvae, small insects, or foul odors caused by buildup, the following sections provide a clear, plug-and-play approach. The goal is to remove the pests, clean the chamber, and prevent future visits from these unwelcome guests.
Quick Answer
Clean the disposal with a dedicated brush, reset the mechanism if needed, and use a drain snake to clear clogs. Flush with cold water, run the unit, and deodorize with citrus peels or a baking soda-vinegar combo. If pests persist, inspect for leaks or trapped food and consider a maintenance kit for ongoing care.
What You’ll Need
- Garbage disposal cleaning brush nylon bristles
- Garbage disposal reset wrench Allen key 1/4 inch
- Garbage disposal drain snake 3 ft
- Garbage disposal plumber’s snake flexible 3 ft
- Garbage disposal maintenance kit with wrench and brush
Before You Start
Before attempting any work on a disposal, ensure the power is off at the wall switch and, if possible, at the circuit breaker. Never put your hands into the grinding chamber. Prepare a dry, clean workspace under the sink, and have a flashlight handy to inspect for food residue, mold, or damaged seals. Time commitment: 20–45 minutes for a thorough cleaning and inspection. Critical cautions include keeping the unit unplugged, avoiding harsh chemicals, and not forcing tools into the disposal when power is on.
Step-By-Step: How To Get Rid Of Bugs In Garbage Disposal
- Turn off the power at the switch and unplug the unit. Verify no power is reaching the disposal.
- Remove standing water and visible debris from the sink area to reduce further attraction for insects.
- Open the disposal chamber access port if your model has one, and use a garbage disposal cleaning brush to scrub the inner walls and baffles.
- Run cold water while rotating the disposal switch. If a reset is needed, insert the garbage disposal reset wrench Allen key 1/4 inch into the reset button to restore factory settings.
- Insert a garbage disposal drain snake 3 ft or a flexible plumber’s snake into the drain to dislodge any stuck food, roots, or buildup causing poor drainage.
- Twist and pull the snake out slowly, then run cold water again to flush loosened material through the pipes.
- Pour a brief, light cleaning solution into the disposal, such as a mix of baking soda and water; follow with a few squeezes of lemon or citrus peels to deodorize.
- Reinstall the disposal cap, restore power, and run the unit with cold water for 20–30 seconds to clear any remaining debris.
- Check beneath the sink for leaks or damp cabinets; tighten fittings if needed and ensure the seals are intact.
- Repeat the process monthly as part of routine maintenance to prevent recurring pest issues and keep the disposal clean.
- If pests persist after cleaning, consider using a dedicated maintenance kit to simplify future upkeep and maintain proper lubrication of moving parts.
- For stubborn clogs or recurring infestations, consult a professional plumber to assess plumbing connections and drain lines.
Troubleshooting
| Symptom | Likely Cause | Fix | Prevention |
|---|---|---|---|
| Disposal won’t turn on | Electrical reset needed or switch tripped | Use garbage disposal reset wrench Allen key 1/4 inch to reset; check breaker | Keep switch and outlet dry; avoid splashy sinks |
| Persistent bad odor | Buildup of organic matter | Clean with garbage disposal cleaning brush nylon bristles and citrus deodorizer | Run disposal regularly; avoid dumping fibrous waste |
| Slow drainage | Clog from food debris | Snaking the drain with drain snake 3 ft or plumber’s snake | Dispose of in small pieces; run cold water after use |
| Recurring bugs | Moist environment or hidden residue | Deep clean; check seals; use maintenance kit | Keep area dry; fix leaks promptly |
| Leaks around disposal | Loose connections or worn seals | Tighten fittings; replace O-rings if needed | Inspect periodically and replace aging parts |
Common Mistakes
- Using hot water exclusively to flush a disposal, which can loosen grease and cause clogs later
- Trying to force objects down the disposal rather than using proper tools
- Pouring chemical cleaners into the disposal, which can damage seals and pipes
- Ignoring persistent odors or slow drainage—these signal deeper issues
Tips For Best Results
- Run the disposal with cold water to help solidify and flush waste through the trap
- Regularly use a dedicated brush to scrub the interior during cleanings
- Maintain a light, fruity deodorizing routine with citrus peels or baking soda
- Keep up with preventive maintenance using the included maintenance kit with wrench and brush
Call A Professional
Stop and call a pro if there are signs of serious damage, continuous leaks, unusual noises, or repeated failures after routine maintenance. Do not attempt to disassemble components beyond basic cleaning, and avoid electrical work beyond basic resets if you’re unsure.

Buying Guide
When choosing tools for ongoing disposal maintenance, consider size and compatibility with your model, ease of use, and the availability of a maintenance kit that includes a brush and wrench. Look for a compact drain snake that reaches typical pipe depths, and ensure the kit can handle standard Allen key sizes. Noise should be minimal during operation, and energy use should align with your household practices. Consider placement under the sink and whether the kit includes guides or diagrams for quick reference. A well-rounded kit can simplify routine cleanings and reduce pest-related issues over time.
