I put Cimexa down 2 days ago. I just vacuumed and saw more fleas than I normally do when I went to empty the container. Is this normal? I would also like to know how long Cimexa takes to kill a flea?
It can be normal to see more activity after applying a product like Cimexa Dust as the fleas can become irritated and more active due to the product. When pests come into contact with CimeXa dust, the product clings to their exoskeleton and absorbs the waxy coating, causing death from dehydration. Cimexa does not kill immediately but instead will take several hours to actually kill the fleas. With fleas, the main part of your treatment is vacuuming. Vacuuming pulls fleas and eggs to the surface and also provides the stimulation the pupa (immature flea) need to exit their cocoons and expose themselves to the insecticides that have been applied. This could actually be the reason you are seeing more fleas in the container than before.
