This will not poison her. The only thing we need to worry about is that she ate the plastic which could be sharp.
The poison is not harmful to dogs.It is a neonicatinoid (nicotinic receptor agonist) in the same catagory as imidacloprid (Advantage) and it is actually the active ingredient in Vectra 3d
More here on this drug:
For the most part these roach traps are not toxic to dogs. If the dog ingests large numbers of them, then there might be more cause to worry, but just one or two should not contain enough poison to do anything at all. However, if your dog ingests the plastic portion, it can cause an intestinal obstruction . You can read about these and they symptoms of them on this website.
Immediately give her some spongy food like cottage cheese,fiber bread, pasta, mashed potatoes to try and push it through. You can also put a dollup of plain vaseline on her paw for her to lick off. ASAP sprinkle a half teaspoon of metimucil on her food just in case of anything jagged That will make a cocoon around it and protect her GI tract.
It can take up to 30 hours to pass it. Keep an eye on her stool to make sure she does. If she develpes any constipation or abdominal pain, lethargy or pale gums blood in stool or in vomit she should be seen ASAP or will not eat or vomits food back up.
I will be here so please let me know how she is and when it passes.
I hope your baby will be fine.
