Best cockroach foggers
The honest buying guide for cockroach foggers is short: for German cockroach, a total-release can is usually the wrong purchase. The droplets do not reach the crack, and the repellency undoes gel bait. The can is in the catalog because people buy it. If the label use is an empty, enclosed room and you will leave as the can requires, this is the product. Otherwise buy bait.

Which one to buy
Labeled product
Hot Shot indoor insect fogger
The can people search for — Hot Shot-style total release. Cover aquariums, kill flames and pilots as the label says, leave, and stay out for the stated time. Poison control in the US: 1-800-222-1222. This is not a kitchen plan for German cockroaches.
Labeled product
Combat Max cockroach gel bait (syringe)
Best instead — Spend the fogger money on gel and a flashlight. Dots in cracks beat a cloud in the open air.
Hardware
Sticky cockroach / insect monitors
Best way to see if it failed — If nymphs are still on the card, the fogger did not reach the harborage. That is the usual result.
Why the can is a safety purchase as much as a pest purchase
Total-release foggers have started fires and have driven people out of buildings when the room was not actually empty. The label is not a suggestion about pilots, gas, and the time you must stay away. Do not fog a room you cannot leave. Do not fog a room with a bird, a fish tank you cannot cover as the label requires, or a person who cannot exit.
If you already fogged and the roaches got worse, stop spraying and switch to bait in cracks. More cans will not reverse a scattered German population.
Common questions
What is the best fogger for roaches?
For German cockroaches in a kitchen, none. Buy gel. A total-release can is a labeled empty-room product with fire and exposure rules, not a harborage treatment.
Can I fog and use gel the same day?
Do not. Repellent residue keeps roaches off the bait. If a room was fogged, wait and then bait the cracks the fog did not reach.
Will a fogger kill roach eggs?
Not the eggs tucked in a hinge the droplet never touched. That is why nymphs return and why bait plus an IGR is the kitchen sequence.
