Bifen IT cannot be applied to edible vegetation. We would recommend using a product like Fertilome Tree and Shrub Systemic Drench. This product is labeled for boring weevils in Pecan trees.
Bifen IT is not designed to kill on contact and even when you spray an insect directly it can take several minutes or longer to kill it. It will help to kill the ones that contact a treated surface as well as their food source, but how long it takes to kill after application depends on age and health of the insect, how long after application they contact the treated surface and how long they spend on the treated surface. Spiders themselves are harder to kill as they do not groom themselves and have the long legs to keep themselves off the ground and in more contact with a treated surface. We have a great guide here for treating spiders that might also help. If you are going to be spraying spiders directly each time, you could add a product like ExciteR to Bifen to give it a faster initial knockdown only.
Bifen IT is for insects only and will not treat fungus or other causes of spots on plants. It is important to identify the disease on your plants so that you can select a product that will work for your needs. You can contact your local cooperative extension office and speak to the master gardener on staff for help identifying the type of disease on your plants
Bifen I/T is a great product for earwigs and a large variety of other insects as well. You will spray Bifen indoors around baseboards and cracks and crevices, and outdoors around window and door frames, and around the foundation of the home 2-3 feet up on the side and 2-3 feet out on the ground. Earwigs like moisture and dark areas so if you have any mulch or pinestraw against the home or close by in the yard, turn those areas to help dry them out and soak them down with the Bifen to help kill anything living there. Children as well as anyone other than the person applying the product need to be out of the area being treated while the product is being applied and until everything is fully dry. Once all surfaces are dry it is completely safe for everyone to return.
You do want to spray Bifen IT over the sod periodically to keep the rest of the population on top of the new sod down.
We recommend removing the Hermit Crabs from the rooms till after the application of Bifen IT has had time to dry.
