Insects for Homestead Chicken & Fish Feed

Why insects?

Insects turn low-value organic leftovers into high-value protein and fertilizer, closing loops at village scale. Black soldier fly (BSF) larvae, for example, eat food scraps and agro-wastes, their dried bodies become feed, and their frass is a plant-boosting soil amendment. A Windhoek enterprise (Biocycle) already does this at small industrial scale, diverting ~60 t/month of organic waste into 6–8 t of feed and fertilizer, and selling BSF products to local chicken and pig farmers; the same model can be miniaturized for homesteads.    BSF frass improves soil health and can suppress some pests and diseases compared with conventional fertilizers in research trials. 

Species used most often—and available in Namibia

1) Black soldier fly (Hermetia illucens)

Use: Dried larvae or meal for poultry and fish; frass as fertilizer.

Why it works: Fast growth on mixed organic waste; high protein and lipid content.

Namibia notes: Occurs in northern Namibia and is being farmed in Windhoek; products are sold locally for chickens/pigs and targeted for aquaculture as it grows. 

Fish evidence: Multiple studies across Africa show partial to total replacement of fishmeal with BSF meal in tilapia without growth penalties; Zimbabwe trials in 2025 confirmed viability for local aquaculture. 

2) Housefly (Musca domestica) larvae

Use: Fresh or dried “maggots” for poultry; can also go into fish feed.

Why it works: Easy, low-tech rearing on clean organic by-products; ubiquitous species.

Namibia notes: Musca domestica is recorded in Namibia (national biodiversity database). 

3) Termites (Macrotermes spp.)

Use: Trapped or collected soldiers/alates for poultry; termite meal has also been trialed in fish feeds.

Why it works: High protein; culturally familiar collection methods exist across Africa.

Namibia notes: Macrotermes michaelseni and other Macrotermes species are widespread and well-studied in Namibia. 

Evidence: Poultry growth improves with Macrotermes supplementation; studies also show feasible partial fishmeal replacement in tilapia and other fishes. 

4) Mopane worm (Gonimbrasia/Imbrasia belina) – seasonal caterpillar

Use: Dried caterpillars can supplement poultry feed (where sustainably harvested); frass not applicable.

Namibia notes: Major seasonal resource in northern Namibia; extensively harvested and traded in the region. 

5) Grasshoppers/locusts (Orthoptera)

Use: Sun-dried and milled into seasonal poultry feed.

Namibia notes: Brown locust (Locustana pardalina) outbreaks occur in parts of Namibia; desert locust subspecies S. g. flaviventris occurs in southwest Africa. 

Other farmed insects like mealworms (Tenebrio molitor) and crickets (Acheta domesticus) are widely used globally; they can be reared in Namibia with controlled housing and clean feed, but local supply chains are less developed than BSF/housefly at present

Namibia’s legal situation (commercial feed)

Bottom line: Insects can form part of commercial feed diets in Namibia if the feed (and ingredient) is registered and complies with safety rules—there is no Namibia-specific law that bans insect protein for non-ruminants such as poultry or fish.

• Namibia regulates feeds under the Fertilizers, Farm Feeds, Agricultural Remedies and Stock Remedies Act, 36 of 1947 and its regulations. Feed products/ingredients must be registered with the Registrar (Ministry of Agriculture, Water and Land Reform) before sale/import. 
• The FAN Meat scheme (industry standard) reiterates national rules and explicitly bans ruminant-derived proteins in ruminant feeds and chicken manure, primarily for BSE and food-safety reasons—not a ban on insects for poultry/fish. 
• In practice, a Namibian BSF producer already sells insect-based livestock feed locally (poultry/pigs), indicating regulatory feasibility when products are registered and produced hygienically. 

Context: Internationally, the EU authorized insect processed animal proteins for aquaculture (2017) and later for poultry and pigs (2021), signaling maturing safety frameworks; Namibia hasn’t issued insect-specific feed rules, so operators follow the general feed-registration and hygiene laws. 

Key compliance points for Namibia producers/homesteads scaling up to sales:

• Register the feed/ingredient and comply with hygiene/traceability requirements. 
• Avoid any inclusion of ruminant proteins in ruminant feeds and avoid chicken manure in feed per FAN Meat. 

“Treasure from trash”: homestead & village setups

Black soldier fly (most practical starter):

1. Inputs: Fruit/veg scraps, spent grain, clean canteen waste; avoid substrates contaminated with pesticides/heavy metals or raw human/ruminant feces. (Safety reviews document potential transfer/accumulation of contaminants.) 
2. Process: Hatchlings on bran, then larvae on mixed organic waste; harvest prepupae; oven-dry/sun-dry before feeding or milling; use frass on fields. (Local workflow documented by Biocycle.) 
3. Use: Replace part of poultry/fish protein; start low (5–15% of the ration) and monitor performance. Evidence supports higher inclusion in aquaculture; homesteads should scale cautiously. 

Housefly larvae (low-tech maggots):

• Simple buckets/cages can convert clean by-products into larvae for chickens. Ensure heat-treatment or thorough drying before feeding; keep systems hygienic to limit nuisance flies/disease. (General risk and hygiene guidance from EU/industry reviews.) 

Termite trapping (for poultry):

• Traditional traps: place inverted clay pots or containers filled with moistened plant material near mounds; collect soldiers/workers after a few hours; feed fresh or sun-dried. Methods validated with smallholders in West Africa and transferable where Macrotermes occurs (incl. Namibia). 

Mopane worms (seasonal supplement):

• Where legally harvested and sustainable, sun-dry and crumble into rations; avoid overharvesting and respect local tenure rules. Namibia and neighbors have decades of experience and scholarship on sustainable harvesting. 

Safety essentials (don’t skip)

• Substrate safety: Insects can concentrate heavy metals/pesticides if the waste is contaminated; choose clean feedstocks and keep records. 
• Hygiene & processing: Follow good hygiene practices (GHP/HACCP); thermal processing/drying reduces pathogens; separate clean and dirty zones; maintain traceability. (IPIFF good practice guides.) 
• Allergens: Insects can trigger shellfish-like allergies for some workers/consumers—use PPE during processing and label clearly if selling.
