Can Maggots Live in Coffee Grounds?
In short, yes, and it’s not uncommon. Most used coffee grounds are moist vegetable matter and make a good breeding ground for insects and bugs. Tiny ones can slip into anything not sealed entirely airtight. The reality is that insects and bugs are already on your coffee beans before harvesting and if they get caught during the process they will be roasted together. But this is nothing to be afraid of and you shouldn’t panic about it.
Insects form the vast bulk of all life mass on earth by weight. There are always some around.
If the maggots are alive then you most likely have insects coming into your house. If they’re dead then they’ve been in there for a while, most likely before the package was even sealed.
You might not want to know this but you’re constantly consuming insects and bugs in your food & drinks. There are standards for allowable insect and vermin contamination in food because some are unavoidable. As long as things are processed to kill all microbes then it’s just a matter of a “don’t ask and don’t tell anyone.” scenario.
Yes, brewing coffee kills any insects/eggs in the coffee beans but it doesn’t mean they’re not there.
What Can You do to Avoid Maggots in Your Coffee Grounds?
One solution is to dry your coffee grounds to make them unsuitable as a breeding ground. Spread it out on a tray/plate and they will air dry in a day, no need to run a dehydrator. The other thing you’ll have to do is to remove all moist trash from the house within a day.
Besides drying you can also get a sieve that’s big enough for your coffee grounds to go through but not big enough for the maggots. This ensures to get the maggots out of there before brewing your coffee.
Maggots in Your Fertilizing Coffee Grounds
Coffee grounds are a fantastic fertilizer for your garden and compost pile. It’s likely you will find maggots in this scenario and it’s honestly up to you if you want to keep them there or not. Maggots can be better than earthworms in the early stages but some people prefer to not have them there at all.
The Bottom Line
Insects and bugs are constantly on your coffee beans before harvesting and thus it’s not uncommon for them to get roasted together with the beans. Most used coffee grounds are moist vegetable matter and make a perfect breeding ground for them and any packaging that’s not sealed completely air-tight means you can find maggots in it at some point.
There is no reason to panic, this is just nature doing nature things after all.
