Prothor SC 2

Prothor SC 2

PRODUCT DESCRIPTION:     Odorless  concentrate classified as a “non repellent” which means insects won’t know its present where applied. This means you can use this active without spooking or chasing insects elsewhere. Designed for use inside crawlspaces, under foundations and around the home, Prothor is a good active for “communal” pests like termites, ants and most any garden or turf pest around the home like grubs and beetles.

WHERE TO USE IT:    Inside the home Prothor can be applied to structural members infested with wood destroying pests, wall voids and sub-slab for termite prevention. In the yard, treat the soil around the home as well as grass, mulch and gardens. Prothor can also be used as a systemic on trees and shrubs for long term control of wood boring pests and insects which target plant foliage.

RATE OF APPLICATION:     When spraying it out over grass or foliage in a standard PUMP SPRAYER, add  .3 to .6 oz per gallon of water.

When treating ants in the yard, add 2.5 oz to our 20 GALLON HOSE END SPRAYER and then fill the sprayer up to the 5 gallon line. Hook the sprayer to a garden hose and spray the entire tank over 5,000 sq/ft. Retreat monthly when ants are seen until they are gone. Once gone, treat every 2 months to ensure they do not return.


When soil drenching shrubs and trees, use .1 – .2 oz per inch of tree diameter. So 1-2 oz per 10″ of tree width. Add the chemical to a 5 gallon bucket filled with 3-4 gallons of water. Make 4-8 holes for every bucket you need to use so for a tree 20″ wide, you should use two buckets and 10-15 holes around the tree. Use a stake, something like rebar, to create holes 1-2 feet deep. The liquid should then be poured out over these holes slow enough so the holes will absorb the fluid evenly. Drench within the “drip line” of the tree limbs but not closer than twice the width of the trees trunk to the base of the tree. So if the drip line is 10 feet out from the trunk and the trunk is 2 feet wide. drenching 4-6 feet out from the trunk would be fine.

When treating for termites, mix 1 oz in 2 gallons of water and apply the 2 gallons of mixed solution to every 10 feet of foundation around the structure. Dig a small trench prior to treating to insure the material stays in place during the application. Retreat every 5 years.

For flower beds, plant foliage and turf, .3 to .6 oz per gallon of water per 1,000 sq/ft will control most pests.


TARGET PESTS:   Adelgids, Ants, Aphids, Billbugs, Carpenter Ants, Chafers, Chinch Bugs, Cutworms, Grubs, Japanese beetles, June Beetles, Lace bugs, Leaf beetles (including elm and viburnum leaf beetles), Leafhoppers (including glassy- winged sharpshooter), Leafminers, Mealybugs, Oriental Beetles, Psyllids, Sawfly Larvae, Thrips (suppression), Weevils, Whiteflies, Wood Borers and Woolly Adelgids just to name just a few.

Is Prothor the best spray to use for cicada killers? I have been battling them for weeks with Drione dust, but there are more wasps and burrows than I can keep up with. I recall seeing a video, I believe, that suggested spraying Prothor after the nests were treated. Please email me so we can start up a conversation about my best next move.

Great spray! This spray works great. We bought it for leaf eating bees that were eating the the leaves on our eastern red bud tree. Finally no bees. The delivery was slow. Ordered it on the 1st of technology month and received it 14 days later. That was not a 2 to 4 day delivery.

I reached out to after a loosing battle with leaf cutter bees invading my front walk. Prothor was recommended to me. It did the job quickly and with only one application. It was a good purchase. I have plenty left over to treat again just before their yearly arrival.

What the Doctor Ordered! My sandy pool area was a playground of about 100 black w. white striped ground digger wasps for several weeks. They have stingers, but happily ignored us. But bare feet couldn’t ignore them anymore. I gave a 5% spray to the sandy areas that had their nesting holes. Voila! The number of wasps are now way down to a tolerable few.

I had an issue of cicada killers nests around the base of three foundation plants. Used the Prothor as directed with a tank sprayer around the base of the plants for two days. No more of these annoying insects after that ! Definitely recommend where using powder would be difficult to apply.

This product seems to be helping with Jadera Bugs..I just bought a second spray. Do you have any suggestions about what to do about a golden rain tree..short of cutting it down!

Couldn’t be happier! This product is fantastic. I followed the directions for use and applied as instructed. I couldn’t believe how quickly I saw results. Follow the instructions and application directions and you should also be very pleased with the results!

So far so good.. After trying the powder and not getting all of them, the bees came back with bigger holes as described on this site. We used this product a week ago and so far so good. We had good weather, perfect spring – 60’s and low 70’s. Using spray bottle and long nose we sprayed down the holes and on the grass area. We then watered to help soak into the ground. Fingers crossed they are now out of our grass.

We had hundreds of wasps that were outside a third floor screened porch. We sprayed Prothor SC from the inside of the porch, through the screen onto the eaves and ledges outside the screen. That way the outside wasps carried the Prothor SC back into their nest and within three days all wasps were gone. Worked exactly as Bug Spray employee told me it would. Now we can enjoy our porch. Awesome product!

Can you use Prothor 200sc indoors for the Treatment of ants?

Janet Maulbeck @ 7:14 am #


So far so good. Well we sprayed every place we had digger bees and holes and so far we don’t see any bees but I think it’s going to take some time before I know for sure if it works. We do have very high hopes though. Everything else we tried, we saw these digger bees and new holes the very next day but so far we don’t see any bees or new holes.

We have what I believe to be morter bees on a top porch above the door. Will this take care of them?

I have fire blight which has already killed a 20 year old apricot and 20 year old black walnut over the span of three weeks. Will Prothor work on fire blight which looks like it is spreading to surrounding trees?

I have an Ash tree but I’ve been noticing for quite some time that the top of the trunk and some branches are very black, like burnt. Is that fungus? How do I treat it and what is the best time of the year to do it.

Will Prothor control gall wasps on bur oaks?

I bought prothor 3 days ago to kill digger/miner bees and have applied it two evenings in a row. I’m still seeing new holes in my mulch beds and turf.

We have oak galls on our 3 red oak trees. Each tree has a 24 inch diameter, 7 foot circumference and are about 45 feet tall. We have many of the galls on all 3 trees which first appeared this spring. Should we treat them now? Can we spray on the surface or should we dig holes around the tree? How often do we spray and when? How much product is required for each treatment and what is the cost?
