We have a horrible problem with mayflies on our house this summer. We know where they’re coming from and usually they just stay over there by the drain ditch. But we’ve been getting a lot of rain this year and now I think they might be nesting on my house! We get thousands all over everything and its so messy. What can we use to keep them away?
Mayfly swarms are usually short lived and in most regions of the country, only last 2-4 weeks. But this year has been bad.
To keep them off the house, spray all the siding with MAXXTHOR EC. These treatments will both kill and repel all insects and treatments should last 2-4 weeks.
Use .5 oz per gallon of water and apply it with one of the sprayers below. Our Green Topped Sprayer is well suited for the task since its nozzle can be removed enabling it to spray as high as your hose would normally spray.
Mix 1 oz per gallon of water and start by spraying as high as you see them active. Expect to use 2-3 gallons to treat most any home needing protection.
This is probably the best sprayer for the job, our GREEN TOPPED HOSE END.
You can use any standard PUMP SPRAYER to make the application.
Now if you don’t feel like pumping and pumping a regular pump sprayer or if you need to reach high parts of the home, consider getting one of our NO PUMP SPRAYERS. This unique sprayer is simple yet very good, easy to use and one of our “favs” for applying insecticides to your homes exterior and landscape (its too powerful for use inside).
Ideally suited for reaching heights of 40+ feet, it has no moving parts other than the valve you hold for spraying and the adjustable brass “bullet” nozzle.
This sprayer is essentially a tank that can hold water, chemical and up to 130 psi of air. The top lid has a clamp and rubber gasket that seats on the “inside” of the sprayer so as you fill it with air, the seal will naturally remain in place, nice and tight.
The following video gives you the overview of how this sprayer works.
The top has 3 “ports” (pic below). The port to the far left is used to fill the tank with air. Using any electric air pump (the kind you would use the fill tires on your car), you can safely pressurize this sprayer up to 80 psi. The tank is rated for up to 130 lbs but the relief valve will only allow you to fill it to 80-90 psi before it starts to release. This happens as a safety precautionary action.
For normal use around the home, 50-60 psi should be enough for you empty the liquid from the 2.5 gallon tank assuming you only add 1 gallon of mixed product. True, the sprayer can “hold” 2.5 gallons of liquid but you need room for the air. Our tests show that 50-60 psi will pump out an entire gallon of spray allowing you to reach 25-30 feet heights.
For reaching 40+ feet or higher targets, pressurize the sprayer to 80 psi and again, mix up only what you plan on using and no more than 1 gallon of mixed solution at one time so the tank has enough room left to store all the needed “air”. One charge of 80 psi is enough to get the entire mixture to spray out so you don’t have to be concerned about constantly recharging.
The 5 GALLON NO PUMP can hold over 2 gallons of mixed material and can perform equally as well.
Remember, YOU WILL NEED AN AIR COMPRESSOR POWERFUL ENOUGH TO FILL THIS SPRAYER!! WE RECOMMEND ONE THAT CAN DO AT LEAST 100 PSI.
3 GALLON SETUP (remember to only fill it with 1 to 1.5 gallons of mixed solution to leave room for air)

BEST MAYFLY SPRAY FOR THE YARD
Out in the yard, addressing their nest site will help cut back their numbers too. Since mayflies like to lay eggs in and around water, you’ll need something safe enough for use up to the waters edge. For these areas, use BITHOR applied in one of our mist blowers.
Bithor is odorless and one of the rare products that will kill both adults and eggs as it uses two actives. It can be used in place of the Maxxthor for on the home so if you decide to fog, using Bithor on the home and yard will get the job done for sure.
The following “short video” (less than 60 seconds long) explains how safe Bithor is to use in and around the home.
Mix 1 oz per gallon and plan on misting 1 gallon of mixture per 1/2 acre. Treatments will be weekly until you’re not seeing the swarms and expect to use 1 gallon per 1/2 acre when applied using one of our MIST BLOWERS. Bithor will work quickly and both kill mayflies immediately and prevent them from reproducing successfully. Expect to treat once a week when they’re active.
For 1/2-1 acre lots, our BUGSPRAY FOGGER will do a good job. It will blow out a mist 30-40 feet and pumps a gallon every 10-12 minutes.
The following “short video” (less than 60 seconds long) shows this fogger being used around the home.
As you can see, its both light enough to be used easily yet powerful enough to get the job done efficiently for properties up to an acre.
For 1-2 acre lots, our gas powered BACK PACK MIST BLOWER will be better suited. This unit runs off gas, has a 3+ gallon tank and will blow the mist 40-50 feet.
