Why Are My Ants Not Eating?
Antkeeping is an exciting and rewarding hobby. However, sometimes new antkeepers run into an issue where their ants don’t seem to be eating. This can be frustrating and even concerning, especially if you’re trying to grow a healthy colony. The good news is that there are several common reasons why ants might not be eating, and most of them are easy to fix. Here’s a detailed breakdown of why your ants might be refusing food and what you can do to address the problem.
1. They May Be Full
One of the simplest explanations for why your ants aren’t eating is that they simply aren’t hungry. Young colonies, especially those with only a few workers, don’t consume food as rapidly as larger colonies. They have limited stomach capacity and will only take what they need or can feed to their queen and brood.
If you are feeding your ants sugary foods, such as honeywater or sugarwater, you can check if they're full by looking at their gasters (the swollen rear section of their body). If their gasters appear expanded and shiny, it’s likely that they have already filled their social stomachs and are storing the extra food for later. Similarly, if you have seed-harvesting ants, you may notice that while they take seeds back to the nest, they don’t always consume them right away. They may be stockpiling seeds for future use. This is nothing to worry about! Just make sure there's always dry, whole seeds stockpiled. Shredded seeds means they've been eaten.
What you should do: Continue offering food regularly, even if the ants don’t seem to be eating right away. Overfeeding ensures that they always have access to food when they do need it, but be mindful of cleanliness. Uneaten food should be removed to prevent mold and bacteria growth in the setup.
If they're refusing protein, this may be because the larvae have eaten enough. Continue to offer protein regularly (as this can help stimulate more egg-laying), but remember to remove old food before it molds.
2. They May Not Like the Food
Ants can be picky eaters, and different species have different dietary preferences. Some species thrive on protein-rich foods, while others need a steady supply of carbohydrates to stay active. If your ants aren’t eating, they might not be interested in the type of food you are offering.
For example, fruit flies are an excellent protein source for most ant species, but some ants might prefer mealworms, crickets, or even some kind of table scrap like cooked eggs. Experimenting with different food sources is key to finding what works best for your colony. When it comes to sugars, one somewhat common mistake is giving your ants pure honey. While honey might seem like a natural choice, its thick consistency makes it difficult for ants to consume. Instead, dilute it with water to create honeywater or opt for sugarwater, which is easier for ants to drink.
What you should do: Try offering a variety of foods and observe which ones your ants prefer. If they ignore one type of food, switch to another option. Providing VARIETY ensures that your ants receive a balanced diet while also helping you discover their preferences.
3. They May Be Dehydrated
Water is crucial for ant and insect survival. Even if you’re offering plenty of food, ants may refuse to eat if they don’t have access to moisture. Dehydration can cause ants to become lethargic, reducing their interest in food, and in extreme cases, can lead to death within a short period of time.
What you should do: Ensure that your ants always have access to a water source, such as a test tube with water. Regularly check water sources to make sure they haven’t dried up. Usually, direct drinking water is not enough. Drinking water from a feeder won't help your ants because they'll desiccate without a humid environment. Instead, use nests that offer options such as water towers or surface evaporation hydration methods. Dehydration is critical and should be fixed immediately.
4. The Food Has Gone Bad
Food left in an ant setup for too long can spoil, grow mold, and/or attract mites and other tiny pests. Even if the food was fresh when you first offered it, ants may refuse to eat it if it has started to decay. Protein sources like mealworms break down somewhat quickly, especially in warm and humid environments.
What you should do: Remove uneaten food within 24–48 hours to prevent mold growth and bacterial contamination. Providing fresh food at regular intervals keeps the setup clean and encourages ants to lay more eggs.
5. Wrong Temperature!
Temperature plays a critical role in an ant colony’s metabolism and activity/growth levels. Many ant species, especially those from warmer climates, require higher temperatures to thrive. Most ants in the US that hibernate still need warmer-than-room-temperature environments to grow! If the temperature in your setup is too low, your ants’ metabolic rate will slow down, making them less interested in food.
What you should do: Research the ideal temperature range for your ant species and consider using a heat mat or cable to maintain optimal conditions. Most ants in the US do best at temperatures between 75–86°F (24–30°C). Some species specialized to warm environments need even higher temperatures. Be sure to monitor humidity as well, as some species require higher humidity levels to stay active, grow, and eat.
6. Health or Setup Issues
Environmental factors can significantly impact your ants' feeding behavior. If the habitat is contaminated with chemicals, mold, or excessive trash/debris, ants may stop eating. Additionally, some setups, such as those with poorly ventilated outworlds, can lead to the growth of deadly fungi.
Another overlooked issue is the presence of residual formic acid. Some ants, such as Formica species (or most ants in Formicinae), spray formic acid as a defense mechanism. If this acid accumulates on smooth surfaces, it can come in contact with the ants which causes them harm. Ensure that surfaces the ants might've historically sprayed or recently sprayed AREN'T the same surfaces you feed them sugars on. Additionally, you could add some material that soaks up the acid.
What you should do: Regularly clean the setup and remove any contaminants. If you suspect that chemicals or fungal spores are affecting your colony, consider relocating the ants to a fresh setup. Providing good ventilation and avoiding excessive use of artificial materials can also help maintain a healthy environment.
Final Thoughts: How to Encourage Eating
If your ants aren’t eating, don’t panic. Most of the time, the issue is easily solvable by adjusting food offerings, providing clean water, maintaining temperature and humidity, and ensuring a clean environment. Understanding your ants’ needs and behaviors will help you create an ideal setup that promotes healthy feeding habits and colony growth.
Remember:
Always offer a variety of food sources to see what your ants prefer. They may prefer different food at different times.
Keep water/humidity sources available at all times.
Remove spoiled food to maintain a clean setup.
Monitor temperature and humidity for species-specific or colony-specific needs.
Check for environmental contaminants that may be harming your ants.
By keeping these factors in mind, you’ll be well on your way to raising a thriving ant colony that eats well, grows steadily, and provides endless entertainment as you observe their natural behaviors!
