Does boric acid kill roaches?

"I've seen roaches in my kitchen and want to try home remedies first. Will boric acid kill roaches?"

Using boric acid for roaches is a common DIY approach, and it can work to a degree. When roaches walk through the powder and groom themselves, it can kill them. However, boric acid often provides limited results because roaches can avoid treated areas, hiding deep in walls, drains, and appliances. Boric acid powder must also stay dry to remain effective, and given that roaches like moist and humid environments, the powder is unlikely to stay dry. What’s more, boric acid is best used in combination with gel baits, and the combination of the two treatments needs consideration.

Here are a few things to keep in mind if you try boric acid cockroach treatments:

• Roaches must come into direct contact with the powder
• Applying too much can make roaches avoid it completely
• It doesn’t reach hidden areas where roaches nest
• It can take time to see any results

In summary, although some people use boric acid to kill cockroaches, these treatments are unlikely to eliminate an entire infestation, nor tackle the root cause of the problem.
