How to Get Rid of Ants and Roaches for Good

Tired of creepy crawlies? Wirecutter's pest expert Doug Mahoney reveals the right way to tackle ant and roach infestations. He offers practical advice and debunks common myths (for example, cockroaches aren’t actually the most radiation-resistant insects!).

Doug's 4-Step Pest Control Plan:

Observe & Identify: Know your enemy! Find their entry points & hotspots. Sawdust + carpenter ants? Call a pro ASAP!Clean Up: Starve 'em out! Secure all food (pet food is a big one!), wipe surfaces constantly. Roaches love protein, ants crave sugar.Seal Entry Points: Block their access! Heavy-duty caulk is your best friend around foundations & pipes.Use Bait (Most Effective!): The ultimate weapon! Baits combine food + slow-acting poison. Ants take it to the colony; roaches share the toxic love (🤢). Place bait where you see 'em most!

Avoid:

Kill-on-contact sprays: These can make ant problems worse by splitting colonies.Bug bombs/foggers: They don't reach hiding spots and are explosion risks."Natural" remedies (e.g., Diatomaceous earth): Often messy and less powerful than bait.

When to Call a Pro: If DIY baits aren't working after a couple of weeks, it's time for an exterminator.
