MUD DAUBER TREATMENTS


Mud daubers are a pest throughout all of the United States. There are several species which are the most likely to nest on your home and these include the organ pipe, the black and yellow, the blue, the potter wasp and the mason species. These wasps are so categorized because they create larva rearing mud tubes in which young develop. You will find these nests on the sides of your home.

MUD DAUBER NESTS

Mud daubers like to construct these nests between brick in the mortar joint, where wood trim facia boards and molding meet and around window and door frames. Their nests are similar yet different. Though they all seem to be the same type of nest, in fact each species has distinct characteristics associated with design patterns of the mud. The easiest to identify is the organ pipe whose nests are long and resemble the way the pipes of an organ sit. Black and yellow daubers build their nests more on top of each other and the other species are different still. Regardless of the way these nests are constructed, mud daubers frighten many people and have been mistaken for termites on too many occasions.

 

MUD DAUBER PROBLEMS

Most mud daubers feed on spiders. Females seek out spiders, sting them and deposit their bodies in the back of a larva cell of their nest. An egg is then laid on the spider for the young to feed. A female will typically have several eggs in a single “pipe” and will have 3-6 pipes per nest. If conditions allow, she may have more than one nest. It is not just coincidence that nests seem to prevail on certain homes. It appears to be homes which are stucco, brick or other porous rough surfaces which they like. It is both easier to build nests on such surfaces as well as the fact that nests seem to hold better once constructed on them. This lends credence to the theory that daubers generated from nests built on such surfaces are more likely to use an identical surface for their own reproduction which further explains why one house may seem to be infested with dauber activity!!

 

MUD DAUBERS CAN STING

Though colorful and sometimes bright in color, mud daubers are not as likely to sting as others. It does have a stinger which is used for it’s food but generally will not use it unless provoked. Their bodies are somewhat frail compared to other wasps yet are wizards at using mud and carrying it around to construct their nests. If your house is serving as the local mud dauber neighborhood, there is a simple way to control them. (Don’t waste your time using the garden hose hoping to chase them away. In case you haven’t figured it out, they’ll be back!

 

BEST MUD DAUBER SPRAY

Viper CypermethrinLike most wasps, they don’t like CYPERMETHRIN. This product is both easy to use and works great at controlling local infestations. Your method of treatment will vary on the time of the year you are treating. If it is spring and they have just begun nest making, simply spray the Cypermethrin on the sides of the home where there is activity.

Pump SprayerHose End SprayerThis can be done with both a HOSE END SPRAYER or a PUMP SPRAYER.

Hose End SprayerHose End Sprayer:  http://www.bugspraycart.com/equipment/sprayers/gilmour-20g-390

 

Though the hose end sprayer is easier to use, it will tend to waste more material since you are applying it so much faster than the pump sprayer. The pump sprayer may not be able to reach quite high enough so you may need both pieces of equipment. Which ever you use, try to get about 500-1000 sq/ft of coverage per gallon of material used. Mix the chemical one ounce to a gallon and start high when treating. This will allow over spray to be efficiently used as it flows down the side of the home.

Most homes need 2-4 gallons to get adequate protection all the way around. Although you may only see activity on one side of the home, try to treat as many sides as you can. This will prevent them from simply moving to the untreated side of your house instead of moving off your property completely. Expect to make applications about once a month throughout the spring and then a few more during the year.

 

DAUBER WASP FREEZE

Sting Ray Wasp FreezeIf you already have a lot of nests, the sequence of treatment should be two steps. First, try to knockdown as many of the nests you can using a stick or some type of pole. Try to use the longest stick or pole you have and don’t be alarmed if you see adults. They should avoid you. If you want some extra protection, get a can of STINGER FREEZE which will drop them as they fly. You may see some larva in the nest as well. They will be white and grub like. Be sure to remove as many of the grubs and as much of the nest that you can reach.

DAUBER AEROSOLS

D-Force AerosolIf you’re not afraid of getting stung, use DFORCE AEROSOL instead of the Stinger Freeze. Dforce will work just as well on their nests and though it won’t drop them instantly like the Freeze, the time needed to spray is short so your chances of having a mud dauber see you is slim.

PT-PhantomAnother aerosol that works great on sensitive surfaces like window frames, boats and places where you can’t spray a liquid or the “wet” Dforce is a product that goes on dry known as PHANTOM. This product is ideal for sensitive areas (like boats) because its odorless and when used properly, will both control and prevent insects from nesting. Mud daubers will many times build their nests on tough to treat surfaces and for these areas, the Phantom is perfect for the job.

MUD DAUBER PREVENTION

In summary, the longest lasting treatment for the beset overall results will be to use the Cypermethrin sprayed on surfaces where nests are likely to be built. This will kill and repel daubers for several weeks and when you need to reach up high or cover a lot of area, the Cypermethrin is the way to go. For small areas, the Dforce or Phantom can do the job and for sensitive areas, go with the Phantom since its odorless and goes on dry.

Mud daubers are persistent once they identify your home as a place they like to nest. But if you’re able to treat early in the spring, you can expect 1-3 treatments to keep your home dauber free for the season. If you have a big infestation, it will require removing active nests and spraying over as much of the home as possible. This will insure they don’t simply move over to untreated areas.

Mud daubers like to build nests in our boat’s folded sails. When we’ve finished sailing we flake the mainsail onto the boom and cover it with a canvas “jacket”. When we return a week later and hoist the sail we often find that mud daubers crept in under the jacket and built nests within the folds of the sail. We need a repellant but we’re reluctant to use any chemical spray or oil that might discolor our sails, or any solid device that could emit fumes under the hot jacket….for the same reason. Any ideas? Is the Waspinator effective against mud daubers?

I have mud daubers making nests in the ground. They leave holes where they enter and exit. I have at least 30 holes and because they are so active I can’t weed or even walk close to where they are. They’re are on the south side of the house so it is all day sun. Help! Thanks.

We have blue mud daubers around the casing of our in ground pool at two corners and we can’t seem to get rid of them. We killed one and compared it to make sure that they are indeed blue mud daubers we need them gone because of allergies and little kids. Please help!!!!!

We live in the country and the wasps are building nests in every can light in our covered decks. I can remove the light bulb, but you have to stick your hand inside to remove the baffle which I don’t want to do. Any type of spray I can use without damaging the light components?

@Tech Support:
Will it kill what is in the mud (nest) also, or do I have to knock down the nest?

@Tech Support:
We bought a can of Phantom and have used it successfully all season…..after each sail we’d spray all edges of the sail cover and also the end access points, including the sail’s luff. Only one mud dauber found its way under our sail cover and that was likely due to: 1) inattention (3 weeks lapse) on our part, and 2) not thinking that a prolonged rain might diminish some of Phantom’s effectiveness. A quick weekly spray does the job and we’ve gone 2 weeks between sprays without any bug access.

I have hundreds of nests up in my attic; just discovered them. They seem dormant at the moment. Should I knock them down and get rid of them or leave them?

@Tech Support: Good information! I have these holes all along the edge of my pond, sometimes going down to the water level and causing the ground to sink in spots. I’ve been filling the holes with Sakrete and filling in the last couple of inches with dirt. I can imagine an archeologist digging up my yard in 200 years and wondering about the meaning of those concrete pillars!

We have a 20′ porch ceiling and mud daubers like to nest on the high walls back there. Can Cypermethrin be used in a power washer….it’s the only thing that will reach that height. And if so what about blowback spray…is it harmful to humans?

Mary @ 7:58 am #

Great info, thanks! Can the Onslaught also be used in and around boats without staining or discoloring the covers?

This is our second summer in our home, which is a log home. Already the mud daubers are out of control. Most of the advice I’ve seen on getting rid of them entails destroying the nests. The problem is I can’t find them. I’ve found a few in boxes in the garage and destroyed them but that’s not even where we have the wasp problem. They swarm the outside walls of the house. They’re always there but I never see any nests on the walls out the house. To make things worse, somehow they get inside. We don’t even open our windows. We run the ac instead hoping that that will prevent them from getting inside but it doesn’t help. The house is brand new and so the windows are in perfect condition and the screens fit perfectly and tightly. Still they’ll be in between the screen and the window. Just now one flew out of the upstairs bedroom and he seemed to come from nowhere. I can hear them buzzing around through the beams in the upstairs bedroom. It’s almost as if they are inside the walls looking for a way out and then eventually get out into the house. I feel helpless. Do you think it’s possible that they have bested in the walls of our home? What should I do?

We have a very large workshop which is overrun with wasps, dirt dobbers and some type of large roach. We can’t enter our garage. We had an infestation of spiders before the wasps and then dirt dobbers moved in. We need a permanent solution. We use the garage for storage, boat, etc. We can spray, apply powder, or whatever and wanted to also know if there was a stinging light we could use as prevention. Please help.

We have a two story boat dock. The biggest problem is wasps of some kind. They crawl down into the cracks on the top deck. The top deck is wood on top and has metal underneath. Do you think they have nests in between the wood and metal? The space is about six inches in height and 32 x 32 feet (length and width). If so, is there a way to treat the dock without damaging fish, etc. in the water? A secondary problem is spider webs. We knock them down and they are back within hours.

About two weeks ago (before my Drione dust shipment arrived) I noticed a carpenter bee flying around two small holes between the bricks in the side of my house. Now the holes are filled with mud which leads me to think it’s actually a mud dauber nest. I have the Drione now, but I want to know if I should poke a stick or something in the hole to break up the mud so I can dust? I just don’t want a swarm flying out at me if I do. Any suggestions?

I live in Florida and have mud daubers all over my home and I’m getting ready to repaint the entire house. The painters will remove the nests when pressure washing the home prior to painting. Is there anything they can add to the paint itself which will help repel the mud daubers from re-nesting all around the home?
