Mealworm feeders: what to look for

Mealworm feeders vary more than their name suggests. Some hold dried mealworms behind a perforated surface; others use a dish that can contain live food. Check that exact distinction before buying, because a feeder that holds dry pieces may let live larvae escape.

Mealworms can be offered more flexibly than seeds under current seasonal advice, but “year-round” does not mean permanently full. Small portions, dry food and regular cleaning still matter.

Best compact covered option: RSPB My favourites

The My favourites feeder has a small hanging body with a protective roof and a feeding surface intended for clinging birds. It can take mealworms or compatible seeds according to the product instructions.

Its compact size is helpful for portion control, while the roof gives some protection from direct rain. It can suit tits and other birds comfortable feeding close to the body.

This is not an open dish for live mealworms, and the roof does not make the contents weatherproof. Confirm the food form before filling and inspect after wind-driven rain. Starlings may still learn to cling, so it should not be bought as a species-exclusion product.

Best simple metal feeder: Gardman suet-treat and mealworm feeder

The Gardman is a black steel hanging feeder with a quick-release top and base. It is sold for dried mealworms or suet treats, with stated capacities of roughly 130g and 560g respectively.

The simple metal body is a useful alternative to an exposed bowl. The removable ends should make it easier to clear fragments from the lower section, and the feeder can be repurposed for a suitable fat food when mealworms are not being offered.

The listed capacity is not a serving suggestion. A full 130g of dried mealworms may remain too long in a quiet garden. Ignore the retailer's antimicrobial coating language and rely on actual washing, rinsing and drying.

Best guarded dish: CJ Wildlife mealworm guardian

This feeder places a dish inside a 27 × 27 × 37cm metal guardian cage. It can hang, stand freely or attach to a compatible pole, and the cage is intended to restrict access by larger birds.

It is the most relevant option for live mealworms because a dish can physically contain them, and it gives Robins or other less acrobatic birds a surface rather than requiring them to cling to mesh.

That dish is also the biggest hygiene compromise. It is a flat surface where food, moisture and droppings can meet. Current BTO advice says flat feeders appear to carry greater disease risk, so use only a small portion, remove leftovers promptly and wash the dish frequently. If that routine is unrealistic, choose a contained dried-mealworm feeder instead.

Dried and live mealworms need different designs

Dried mealworms are light and can blow from a shallow bowl. They work better behind a suitable perforated body or in a covered, deep-sided container. In spring and summer, RSPB suggests that dried mealworms can be soaked to make them easier for nestlings to eat; soaked food should be treated as perishable and offered in particularly small amounts.

Live mealworms need smooth, sufficiently deep sides so they cannot climb or spill out. A live-food dish must be emptied and washed rather than continually topped up. Check the manufacturer's food compatibility rather than assuming any “mealworm feeder” handles both forms.

Never add water to a feeder that is not designed for wet food. Soak a small portion separately and remove anything uneaten.

Which birds use mealworm feeders?

Robins, Blackbirds and Wrens readily take live food, while tits and Starlings may use hanging designs. The feeder shape changes access: clinging birds cope with perforated bodies, whereas a guarded dish can suit birds that prefer a surface.

A guardian may also exclude a cautious wanted bird. Give a new setup time, keep it stable and avoid surrounding it with several busy feeders. If the bird you hope to feed never enters, the cage is not serving its purpose.

Mealworms should complement natural invertebrate-rich habitat, not replace it. A garden with varied planting, leaf litter and pesticide-free areas provides food beyond one predictable station.

Preventing spoilage and mess

Offer enough for a short visit, not a day's reservoir. Remove wet or contaminated mealworms, sweep fragments below and do not leave live food outdoors overnight.

Use a sheltered position, but keep the feeder visible and away from a cat's concealed approach. A roof reduces direct rain only; it does not stop humidity or wind.

Store dried mealworms sealed and dry. Live mealworms require the supplier's care instructions and should not be allowed to escape into the home or garden.

Cleaning the feeder

At least weekly—and more often for a wet dish—empty and dismantle the feeder. Brush out dry fragments first, wash with separate outdoor utensils, rinse thoroughly and dry every component.

On the Gardman, reach both quick-release ends. On the My favourites feeder, check beneath the roof and around the feeding openings. For the guardian, remove and clean the dish separately, then brush cage intersections.

Stop feeding if birds appear ill and consult current RSPB seasonal and hygiene advice before restarting.

Our guide to dried mealworms for garden birds compares suitable pack sizes and storage. The fat ball feeder guide covers another food that can be offered more flexibly outside the seed season. If larger birds dominate, compare the humane options in our Starling-resistant feeder guide, and use the full feeder-cleaning routine for removable dishes and cages.

Frequently asked questions

Can mealworms be fed from May to October?

Current RSPB and BTO advice allows small amounts of mealworms during this period, unlike seeds and peanuts. Hygiene and spoilage checks still apply.

Should dried mealworms be soaked?

RSPB suggests soaking them in spring and summer can make them easier for nestlings. Prepare only a small amount and remove leftovers promptly.

Will a guardian keep every Starling out?

No. It restricts body access, but individuals vary and can reach through openings. Buy it for managed access, not a guarantee.
