Will this be effective if I have previously used a granule insecticide contaning Imidacloprid? Or will the insecticide kill the bacillus in Gnatrol?

Imidacloprid acts on neurons by binding to their nicotinic acetylcholine receptors. Therefore, it should have no effects on the bacillus since this is a bacterium. Although it had been discovered that some cyanobacteria have a prokaryotic homolog of this receptor (and as far as I know there are no data on bacillus thuringiensis) it is very unlikely that you'll have any problems.

I'm sorry but I don't the answer to this technical answer. I just know that it worked here in the office to control our outbreak of the pesky flys.

I'm not completely sure. It works well by saturating the soil and prevents future gnats.

Nylar (pyriproxyfen) and Precor (methoprene) have similar modes of action. Both are IGR (insect growth regulators)--they are not toxic--they disrupt the insect life cycle, preventing them from developing into adults that can reproduce. I am more familiar with Percor and it is quite effective. They are both pretty much harmless to mammals. If you have a pet with fleas you really need to use an IGR in the home everywhere. Put the 1 oz into a gallon of "distilled" water (that way it won't leave mineral stains) and mix. Then spray (with a spray bottle) all your carpets and the corners and edges of rooms that don't have carpets. I spray the parts of curtains that the dogs come in contact with and spray furniture, especially under seat cushions if your pets spend time on your furniture and mattresses and box springs. Precore has a long lasting effect (7-9 months). Don't use anywhere near fish tanks. An IGR is a "must" if you really want to be done with fleas--otherwise they will come back--along with a product like Frontline (there are now knock-offs, since the patent expired) monthly on your dogs (not cats) throughout the flea season. Precore breaks down with sunlight, so it is not good for outdoors (also it can affect honey bees, birds and fish). Also, sunny window areas should be treated more often. There are carpet sprays with Nylar or Precore mixed with insecticide for both short term killing and long term IGR control. I don't like to use those more than absolutely necessary. As a preventative, you can use Precore/water mixture once a year at the beginning of flea season and it will prevent fleas from spreading if one happens to come inside your home.

Hi Susan! Thanks so much for your question. The great news is the Indoor Pest Control Spray is effective in killing carpet beetles. Let us know if we can help with anything else!

Insecticidal soap is not that strong you might want to go with something stronger like a Miticide product also though sometimes the sprays kill on contact but the insects lay their eggs in the soil and just keep multiplying the most effective product would be Bonide Systemic Houseplant Granules this product works in 2 ways it kills the eggs in the soil plus the plant takes the chemical up through its roots and when the bug bites the leaves or stems of your plant they ingest the chemical and die. It is simple and safe to use its in powder form you sprinkle it on the soil and water it in it takes about 2 weeks to kick in but once it does it will 100% get rid of the problem.

I found this product to be VERY effective. No more *new* gnats after 2 weeks. One tip I found online to be helpful is to put a small dish or saucer of apple cider vinegar near the infested plants. Believe it or not, the gnats are attracted to the vinegar and they drown/die in it. I would really hesitate to put a dish of sugar water out. Here in FL, at least, it would only attract more and different pests.

One review states the working ingredient is imidacloprid 1.47% apparently the borer killer.

We tried this indoors (for gnats in potted plants) and out (for grubs because of moles) to no avail. The brand that DID work for us was the Scanmask brand. It's not a spray - it's in a type of 'mulch' that you spread around - but it worked. However, we only used it indoors on the gnats. If you plan to try it - I would recommend that one instead: Dr. Pye's Scanmask Live Beneficial Nematodes - Kills Over 230 Bugs

I don't know about gnats, I never tried it on them. I mainly used this product on my garden to kill aphids, mites and cabbage looper moths. I think it would work on them as it seems to eliminate many of the same type of insects.

I have to agree with the previous posts, although our problem is also bedbugs and I can't vouch for de's effectiveness on roaches. I imagine a powder might be too thick, but I kind of doubt it. Remember to use a protective mask when using diatomaceous earth.

I used it on these gnats that have occupied one of our floor plants and although it killed the all of the flies, the plant started to dwindle so you may want to consider an alternative means. Perhaps dropping a spider there but thats kind of cruel.

Yes, we have had some horrible infestations in our rental properties. So I have only used this with other means. Make sure you put borax along run sites, under fridge, anywhere they have to pass to get to food source. Then we make sure all food cleaned up under fridge, stove, around toliets ect. Then I put drops of this where there nest are which usually is in kitchen. They track borax to nest which kills babies and the poison kills them. Drastic measures if bad infestation. Hope this helps. I have never had to reapply poison by doing this. But if this doesn't work it could be the neighbors house. I've seen this as well that's a whole nother ball game! Good luck

It will kill Carpet Beetles but it isn't labelled for treating entire carpeted areas indoors. There are more effective products available.

I found that this stuff kills everything. A friend of mine that works for Terminix uses this same stuff and he says it will kill what ever allies you. It creates a barrier and won't let insects cross it.

My experience is with spider mites and aphids, you would have to read the directions for Moths.I think it kills with a Bacteria its not an insectiside. Best Wishes Joe

Yes, the active ingredient Bacillus thuringiensis is effective against fungus gnat larvae. You would put it into the soil rather than spray on leaves, since I don't think it has much effect on adult gnats. Do a search for "Bacillus thuringiensis fungus gnats" for more.

Insects are killed after coming in contact with the powder because it makes microscopic cuts in their exoskeletons and they dehydrate. I've never had a roach problem, but I've used it with great success for flea and ant control. I've read of others having success with roach control. Only use a light dusting, not a thick line, because roaches will crawl around what they see as a barrier. You want them to crawl through it.

The systemic granules will take care of many different kinds of insect pests. They are spread on thhe soil surface and then watered in. They are extremely effective.
