We recommend replacing the Vendetta Plus Cockroach Bait gel and any other roach bait gel every 2-3 weeks or as needed for best results. If the bait has dried out or hardened, it is not as appealing for roaches to feed.
Apply Vendetta Plus Cockroach Bait Gel as a spot or crack and crevice treatment where roach activity has been found. Multiple small placements are more effective than fewer, larger placements. You can use, 6 bait points per 100 sq. ft. (9.3 sq. m.) for light infestations and 12-24 bait points per 100 sq. ft. for heavy infestations. Also, bait points should be 3-6mm (1/8-1/4 in.) in diameter to equal 0.25 to 0.50 g.
Each tube of Vendetta Plus Cockroach Gel Bait has about 30 grams or 30 dabs of treatment in them. One box of 3 tubes should be plenty to start out with.
It would take a large amount of the Vendetta Plus Cockroach Gel Bait to harm your dog, we recommend that you contact your vet if there are any concerns if she does ingest any.
How long it takes to eliminate a roach infestation depends on how large the infestation is, how consistent and thorough you are being with treatments and what products you are using. There is not a set time; it can take weeks or months even to get complete control. Vendetta Plus Cockroach Gel Bait is typically not used alone but in combination with other products. We would recommend one of our roach control kits. We also have a great article for eliminating them that can offer some great advice; you can find it here.
