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
