PRODUCT DESCRIPTION:    Outside only formulation that works on just about any insect pest. Apply it using a good PUMP or HOSE END SPRAYER.


USE DIRECTIONS:     The exact amount of Maxxthor needed will vary depending you target pests and in most cases, if you refer to our article where we list it for use we’ll have the recommended dose, application rate and frequency of treatments.

For most insects in turf and vegetation, 1 oz per 5,000 sq/ft will do the job. This means the 32 oz jug will cover 4 acres so it goes a long way. For tough crawling pests like centipedes, millipedes or cicada’s, 2 oz per 5,000 sq/ft.

When treating pests in thick vegetation, add BOOST (details below) to the sprayer. This will ensure complete coverage whether you’re using the 1 oz per 5,000 or the full 4 oz 10,000. In other words, the 2 oz of Boost per filling of the sprayer will be sufficient.

Basically Boost enables the Maxxthor to better “coat” treated areas and target pests. This will enhance the performance of the treatment resulting in faster kills, better coverage and overall, better results.

How effective is Maxxthor on thrips? We have 5 ficus trees all thrip infested. What application method is suggested for treatment with Maxxthor. Not sure if a pump sprayer would work due to the size of the trees. All trees are trimmed on a regular basis. However, there is one tree that is larger in size in comparison to the others. Any advice would be greatly appreciated. It is sad how the thrips are damaging our trees. Thank you for your assistance.

I’m glad to have the opportunity to review the Bugspray products and customer service. We have only been using their products for about 2-3 weeks, BUT, we are very impressed. Customer service is good, quick and helpful. The Maxxthor EC and granules are definitely helping to eliminate our clover mites. Also, the Bithor and the FS-MP spray. We have had clover mites ever since we moved into our new home in 2016. We have a pest company currently, and had another one. We decided we need to become more pro-active and do something ourselves to help KILL THE CLOVER MITES. I believe with my whole heart, this company and their products is going to be the help we NEED! Thank you, Nancy Carver

I have been doing business with Bug Spray for the last couple years. I highly recommend this company. Their customer service is the best. Lots of companies out there will take days to return an email (if at all) with a question. Bug Spray will get back to you the same day if not within the hour. Excellent customer service and great products too!

It really works! I had a very bad problem with bag worms on my Yews, Arborvitae and now my Cedars. The recommended items from local nurseries did not curb the problem. After doing some research online, I found the MAXXTHOR ED and purchased it. After one time of use, most of the bag worms died. I have some touch up spots that I didn’t reach the 1st time. I am so very pleased with this product. Also I purchased other items of interest. The measuring tool for the product is easy to follow. Not much is needed. It is worth the price of saving my landscape!

I inquired with this company about problems I had with wasps, hornets, and ants on the exterior of my home and an occasional spider on the interior. One spider is too many for my wife. The representative replied quickly and recommended two products. One was Maxthor EC with a sticker for the exterior and Bithor for the interior. One other concern was staining of the siding and other surfaces. The Rep informed me that if water would not stain, these products would not stain. I obtained both of these and applied them according to directions and within two days our problems were solved. Unbelievable! No more wasps nesting and crawling behind the siding or ants running all over the walks and in the garage. If you have similar problems with insects, you can quickly and effectively eliminate them for a fraction of the cost of an exterminating service. It is more relaxing indoors and outdoors without these pests.

Live in Atlanta. Just finished patio last summer. Can’t enjoy because of flies! Will this work for our yard to allow us to use patio? We have nothing but grass and a small water ditch. No shrubs. Tons of flies appear when we have foods or drinks on patio. Also is it good to start spraying in spring before first flies appear?

It works! We had an infestation of boxelder bugs and my husband sprayed this on our cedar siding house and windows and it took care of them. Thank you, thank you!!

jennings @ 4:55 am #

1. How much Maxxthor should I use to mix per gallon of water. I have a 25 gallon sprayer. I have to treat a large area? There are a multitude of target pests including brown recluse. Also if I am targeting active termites in a few old barns, would Maxxthor work for that or is it more preventative?
2. For spraying inside a screened porch would I need to use Bithor instead of Maxxthor or is Bithor only needed when used indoors?

Thank you

We have been using this product for 3 years now. We get it from Bug Spray. This product when combined with other products they carry, works to eliminate the population of clover mites in our yard and in our southern window tracks. Thank you!

Instant results for the fly problem but they slowly come back a week later, I will just have to spray more often…

Great product and company! These guys are legit. The information on their website regarding how to treat certain pests is outstanding, far better than any help or information we receive from our local pest control companies. We had a springtail infestation and the spraying done by a local pest control company did not have much of an impact. Ordered Maxxthor and some additional products as recommended on Bugspray website and applied as they demonstrated. Springtails were gone within a week. Thank you very much, you guys are great!

July 16, 2021

Jame Doe @ 5:14 pm #


This stuff works for springtails! Had tremendous success curbing springtail populations using this product, combined with the granules, interior sprays & dusting, as advised on the site, in just 4 weeks. I’ve gone from seeing dozens of springtails per day inside (all over kitchen counters, in my pantry, baseboards, bathroom, even on the bed) and thousands outside all over my siding, to seeing maybe 1-2 per day max. On some days I don’t see any at all. I used this product over the granules immediately after spreading them. Additionally, whenever I saw springtails on the siding, I would spray EVERYTHING down (siding as high as the stream would reach, paved areas, turf, planted areas – basically every square inch of my 50×100 lot). I sprayed in the early ev! ening when the bugs would be active (8-9pm), checking every evening and re-spraying if I saw bugs, which means sometimes I sprayed 2 nights in a row. The sprayings have become less frequent (1x week), but you have to be diligent to get rid of the springtail problem.

@Jame Doe: Hello Jame, I was wondering how long it took after you started spraying before you didn’t see any springtails outside?

July 28, 2021

Carl Prater @ 6:34 am #


The spray does a good job on grasshoppers that are coming into the yard and flower beds. Worked for 9 days before I had to spray again. They come in from pasture, so it is a constant battle.

How well will this work on the Joro spider? This is the first year they have shown up at my house. They are all over my cypress trees and edge of the forest line and working there way closer to the house. I hate spiders and these give me a grabber. Is this contact only or will the residue also kill them?

I have lived in my home for 4 years. I have wasp arriving starting early spring throughout the summer every year. I knock the nest down they come back. I buy cans & cans & cans of store-bought wasp spray. Worthless!! They come back. I just wanted to cry I could not enjoy my backyard. I purchased MaxxThor and I diluted it in a spray bottle. I sprayed the area that I had the problem & VOILA!! No wasp at all! It was pricey but worth it. Also, it says after spraying MaxxThor will last 3 months. It has been almost 5 months later and still no wasp. I give this 10 stars but only 5 stars is the max(pun intended). MaxxThor is a game changer. BUY IT NOW!!

We have been plagued by copperhead snakes every summer for the past few years. A herpetologist said they were likely after the cicadas in the oak trees in our yard. The Maxxthor pretty much eliminated the cicadas and crickets (another food favorite of copperheads) and we have not seen a snake in the yard since I treated the area. Hopefully this resolves the problem. The literature with the product says it’s ‘pet safe’ for our dogs once it dries, and they seem unaffected. My only concern is the literature does not address how often the area needs to be retreated and does not talk about rain/weather resistance. I intend to retreat every 30 days and wait until there is no rain in the forecast for at least 24 hours. Overall, very happy with the product!

Hello, we are currently battling springtails. They are all over the outside of our homes siding, downspouts, gutters, garage, patio, porch, and driveway. They are starting to come in through our windows even when they are shut, along with our doors. We have the treated the entry points but are looking for a spray that we can use all over the outside of our house which is vinyl siding and partial brick. Would maxxthor be our best bet? Is this safe to use on on vinyl siding? We are at our wits end with these and just need them gone. Thanks for any advice you can offer!

Mike M @ 10:47 am #

@Tech Support:

Great, thank you! I have two more questions for you.
We are currently redoing all of our baseboards in our home. Should we still treat them with the Bithor once laid? And after we complete these treatments, is this something we will continue to have to do the entire time we live here or is there hope eventually these pests won’t be an issue anymore?
