How long does it repel Japanese Beetles for? In other words, how often does it need to be reapplied?

Whenever it rains. The beetles don't respond at once, but the next day they are gone. The beetles are cyclical and are winding down in my area now. There weren't many this year.

I only had to reapply after it rained watering didnt seem to affect the spray but the rain would wash it completly away

I am not sure exactly what you mean. It will NOT prevent insects from walking over where it is applied, but as you mention, if they come into contact with Demon WP they will die soon after. Depending on the insect, dosage, etc. this can take up to 24 hours I have found. Sometimes I will find a bug inside the house that is disoriented and clearly almost dead. This makes them much easier to kill without making a mess. My experience is that when you first start using it, you will find bugs inside your house either dead or almost dead. After a couple weeks, you will stop noticing so many bugs. This may be because the bugs "learn" and stop trying to invade, or it may simply be that you are significantly reducing their population. Either way, it works GREAT. Some bug problems cannot be solved by Demon WP alone, and require other treatments at the same time. However, I will always incorporate Demon WP as an important element to any termination plan.

According to the label, it could be good for up to one year. I would wait and see if it is still effective after all your rain. If you see white flies starting to appear again, then re-apply. I live in So. Ca and we only had 4 inches of rain total this year. When I see the insects re-appearing again, I re-apply.

As far as I am aware, the milky spore is effective against Japanese beetle grubs in the ground. The beetles you see on the rose bushes are in their adult stage. An insecticide effective agains adult Japanese beetles should be used on the bushes. Milky spore is designed to control Japenese beetle grubs in the ground, before they become adults.

The Bottle says it protects for 2 hours... I would suggest twice a day at most... especially for babies... bug are more active in the evening...

I think it depends if you spray early enough. I have used it for years and never had issues, until this year. The flower beds in my new home were infested with just about every kind of bug you can imagine. The Ortho worked on everything except the Japanese beetles, the difference this year is having sprayed in the summer instead of spring. I ended up using Garden Tech's Sevin 5% dust and had great results. I was so fed up as the beetles were annihilating this gorgeous rose bush and I wasn't getting to enjoy it. I doused the bush with the dust, the directions say to use a thin layer. I probably could have gotten away with a thin layer but I was so fed up with those pests. Some of them immediately started to try and fly away others immediately fell off. Within a week the bush looked so much better! There is still damage from the beetles but there has been zero damage to the roses that have bloomed since. I definitely recommend the dust if the beetles are already an out of control issue.

About every 30 days but sometimes I let it go longer. Depends on it I am getting a good amount of insects.

I don't think so. It has pheromones that attract Japanese beetles. I have a lot of June bugs but I never saw any in this.

Ten ounces of the milky spore powder is supposed to treat 2500 sq ft. We applied it in late May and "think" there are less Japanese beetles this year. Maybe they all haven't come out yet.

Each fuel cartridge lasts up to 12 hours. Each repellent mat lasts up to 4 hours. Those are manufacturer estimates, and are roughly in line with what you can expect to see in real use.

It takes a while for this product to work, so the sooner you use it, the better. I bought this product in late July last year and while the Japanese Beetles had already destroyed my lawn at that point, it did help to eliminate the birds pecking at the lawn for larvae. This summer I noticed some Japanese Beetles have returned, but they aren't interested in my lawn but rather my neighbor's fig tree. I've had absolutely no issues with my grass dying or the birds pecking at the lawn and I suspect it is because of this product. I'm not sure how it works, but it's working! I read somewhere that this stuff somehow multiplies in your lawn over time and then at some point needs to be reintroduced (years later). I wouldn't put off on using this.

I feel that it needs to be re-applied about every 30 days. When I was getting ready to leave my last volunteer gig, I let it go 6 or 7 weeks and ended up with a mouse in my 5th wheel. That was after 5 months of 30-day applications and no mice (or squirrels, which the other volunteers battled).

I treated my lawn last year and sprinkled it among my roses and rose of Sharon-they LOVE to MULTI-MATE in the new opening roses--I HATE Japanese beetles!!! I also squish any I can get my hands on-literally- and have also found a direct blast of raid will kill the beetles already on your plants. the treatment did seem to work on the grass. 2 yrs. ago they were SO invasive; last year not quite as bad. I've only seen a couple this year-so far! good luck.

I use it once a week during the warm months; once a month in the winter. We live in the woods, so there always seems to be some kind of bug lurking in the brush, no matter how cold it's been.

yes it would be good after a week. Read the directions and follow the same general guidelines for respraying/treating an area. What ever the time the spray maintains an effectively treatment effect for exterminating the targeted pest would be the same general shelf life of the mixed solution.

I used it for Japanese beetles. It didn't kill on contact, but the next day they would be gone. I cannot tell you if it works on sawfly larvae as we don't grow perennial hibiscus here in Wis. Sorry.

about every 10 to 14 days but after our second application, it's been about a month and still no new roaches
