You've found a method circulating online: mix boric acid with egg yolk, form balls, and place where roaches hide. Let's address this honestly—because while boric acid can kill cockroaches, the method described carries serious risks that many viral posts dangerously downplay.
⚠️ Critical Safety Warning First

Risk
|
Why It Matters
|
|---|---|
|
Boric acid is toxic to humans & pets
|
Ingestion of as little as 5 grams can poison a child; 15–30 grams can be fatal to adults. Symptoms: vomiting, diarrhea, seizures, kidney failure
|
|
Egg yolk bait attracts MORE than roaches
|
Dogs, cats, toddlers, and wildlife may eat these "treats" before roaches do
|
|
"Out of reach" is often not enough
|
Curious pets knock balls from high shelves; toddlers climb furniture
|
|
No antidote exists
|
Treatment is supportive care only—prevention is critical

🚨 The CDC and EPA warn: Boric acid baits should never be made into food-like balls accessible to children/pets. Commercial roach baits use child-resistant containers for a reason.
