The 10 Best Cockroach Gel Baits

For most kitchens fighting German roaches, Syngenta Advion is the gel many pest pros reach for first. Its poison, indoxacarb, turns deadly only after a roach digests it, so the insect has time to crawl home and pass it on. The tubes come with plungers, and the label allows dots in food-handling areas. Some roach strains learn to snub it, so keep a gel with a different poison ready to swap in.

A heavy infestation calls for something that works on two fronts, and MGK Vendetta Plus does. Abamectin kills the roaches that feed, while a growth regulator keeps young ones from growing into breeders, so the next wave shrinks too. MGK says the gel holds its shape in hot spots behind a stove and fits standard bait guns. The growth regulator acts on the next generation, so the full effect takes a few weeks.

If roaches walk right past ordinary gel, try Advion Evolution next. It keeps the slow-acting indoxacarb but mixes it into a new bait recipe that Syngenta says tempts roaches that have turned against sugar-based baits. It was part of the pro gel rotation that cut roach counts within a month in a home trial. Proof of that extra pull comes only from Syngenta's own feeding trials, so the claim rests on the maker's word.

BASF Alpine is built around switching. Its poison, dinotefuran, comes from a different chemical family than indoxacarb or fipronil, and BASF sells two versions with different bait recipes so roaches never settle on one taste. The plan is to alternate them about every six months, and this box is the first version. The two boxes look almost alike, so check the label for Rotation 1 or 2 before you reorder.

Keep Syngenta Optigard on the shelf for the day roaches stop eating your first gel. Its poison, emamectin benzoate, is unrelated to the usual store-gel ingredients, and Syngenta says it spreads through a hiding spot within a day. The maker also rates an opened tube to stay effective for up to three years. It hasn't appeared in any independent home trial, so its record rests on the maker's own data.

Maxforce FC Magnum carries a stronger dose of fipronil than store-shelf gels, about five times the strength. In a home trial, a rotation of pro gels that included it cut German roach counts within a month and kept them down. A dried skin forms on old dots, but roaches keep eating underneath for months. This pack holds just two tubes, and stock is thin.

Schools, day cares and food plants are who Rockwell InVict Gold was made for, since its bait leaves out the eight most common food allergens. The poison is imidacloprid, and Rockwell uses flavors meant to differ from popular gels, which helps when roaches tire of one. The maker says roaches start dying within minutes of feeding. Its poison is a neonicotinoid, so it adds little after another neonicotinoid gel has failed.

Combat Max is the cheap store-shelf option, a single syringe of low-strength fipronil from Henkel. It does work, just slowly. A study in the Journal of Economic Entomology found it needed two months or more to cut roach counts in Kentucky apartments, where pro gels did it within one. For a few roaches in a single room, that pace is fine. A whole-apartment problem can take several tubes and patience.

Think of Maxforce FC Select as the milder Maxforce: the same fipronil at the low strength of store gels, packed four tubes to a box under the Envu name. Envu says the bait stays appealing for a long time and works best when it goes down before any spray. Fipronil is fipronil, so it is a poor switch after a fipronil bait has failed. This pack is new, and stock is thin.

Syngenta Vanecto brings something rare to roach control: a brand-new poison, isocycloseram, in a chemical group of its own. Roaches have had no chance to build resistance to it, and Syngenta says it works on strains that refuse sugary baits. Save it for when two other gels have failed. It is new enough that almost all the evidence for it comes from Syngenta's own trials.
