Conquer Liquid Insecticide - Questions & Answers

Conquer Liquid Insecticide has a shelf life of 3-5 years if kept out of extreme temperatures and direct sunlight.

Yes, Conquer Liquid Insecticide is highly toxic to bees.  If you are looking for something that would not harm bees you could use Mavrik Peirmeter as an alternative. 

Conquer has a very light odor that some folks have described as smelling like dish detergent or as a light insecticide. The smell usually disappears as soon as the product has dried. As for the IGR's, most of them are odorless.

Conquer will kill the roaches and other insects that contact a treated surface but should not be the only product used to effectively eliminate an infestation. We would recommend one of our roach control kits. You can see the kits by clicking on the link here. We also have a great article for eliminating German Roaches here.

Conquer and Archer should be safe on your floors if water is okay to be used on them, but we always recommend testing a small inconspicuous spot first to make sure no adverse affects will take place. That being said, it is very rare to have a flea infestation when there are no carpeted areas for the fleas to harbor, as hardwoods and flat smooth surfaces like that flooring do not provide proper conditions for that insect to thrive. A better option if you do have fleas would be to use one of our flea aerosols like Ultracide to treat your flooring as this will provide you with both the insecticide and IGR(birth control) that you would be getting with the Conquer and Archer, but it will be an easier, cheaper and safer application for your hardwoods. Make sure you are treating all pets with a flea topical like Frontline or our version of it by Martins Flea & Tick, and the outdoor areas the pets travel to prevent them from bringing more in as this would be where they originated. The Conquer and Archer mixture would be a great option for your outdoor flea control. Also, make sure you are vacuuming every day, even with hardwoods as this will help stimulate any eggs to hatch out and be exposed to the product you are using faster. You can see how to do a proper flea treatment in our video "How To Get Rid of Fleas Indoors" and for extra tips see our article on How To Get Rid of Fleas.

Yes, per the Conquer Liquid Insecticide product label:   "For the control of fleas, thoroughly apply a fine particle broadcast spray, using 1 ounce per gallon of water, to infested rugs, carpets, and pet resting areas. The addition of an IGR like Precor IGR Concentrate is recommend when treating for fleas."

Conquer is not actually labeled for wasps or hornets though any wasps or hornets that land on treated areas will surely be eliminated within several hours.

The mixing ratio for Conquer Insecticide is 1 fl. oz. per gallon of water. According to the label, this product can be used for the contact kill of fire ants, however,  it is recommended that you use a product that is specifically labeled for fire ants in conjunction as well.

We would recommend checking out our Fire Ant Guide for tips on how to treat and prevent fire ants.

You would mix 1-2 oz of Conquer and 3-8 ml of Nyguard IGR per gallon of water to cover 1000 sq ft inside for fleas.  You would use the higher rates for heavy infestations and initial applications, and use the lower for follow-up and maintanence as needed.

Conquer Liquid Insecticide leaves a residual after it has dried to keep killing insects including fleas. Be sure reapply every 2 weeks.

You would use 1 oz of Conquer Liquid Insecticide per gallon of water along with 1 oz of Archer IGR as well over 1000 sq. feet. Archer IGR is made for outdoor flea control and holds up well in the sunlight. Please read the product labels for each full instructions before use.

According to the Conquer Insecticide label, TO KILL EXPOSED/SWARMING TERMITES: Use two (2) fluid ounces of CONQUER Concentrate per one (1) gallon (15.9mls/L) of water and apply as a coarse, wetting spray where swarming termites are seen emerging from wood piles, wooden fence posts, wooden structures, or from the ground. This treatment will control the sprayed termites and will not protect the structure from which the swarm is coming. Use only as a contact spray to kill emerging reproductive (winged) and worker termites emerging from infested wood.

For longer control, please look at the Taurus. The Taurus provides best-in-class control of termites, ants and a wide variety of other insect pests including spiders, roaches, ticks and many more. It is labeled to treat for subterranean, arboreal, drywood, and dampwood termites.  Taurus SC is a non-repellent insecticide that is undetectable to target pests, allowing them touch, ingest and spread the insecticide throughout the entire colony. For termites, Taurus SC will eliminate termite colonies in less than 90 days on average, and ant infestations can be controlled in just a few weeks. Please see our Subterranean Termite Treatment Guide and Drywod Termite Treatment Guide for more details.

Conquer does not offer a fast kill. Insects should die within 24-48 hours after contacting treated areas. The active ingredient in Conquer is known to be very irritating to insects and it can cause them to be more active before they are eliminated.

Conquer Liquid Insecticide is labeled for treating spiders. For more information on treating spiders, please take a few moments to review our article on How to Get Rid of Spiders for a successful eradication program.

There really is no valid reason to tank mix Conquer Liquid Insecticide with another insecticide such as Zenprox EC as they are both residual insecticides.  Too much insecticide in an area can make insects avoid it and then neither can do their job.  If you are wanting to add something to Conquer to get a faster initial knockdown during application you would use something like ExciteR.

Yes, you can mix Precor IGR with Conquer Liquid Insecticide.  The Precor IGR is an insect growth regulator and can be mixed with most insecticides to stop the insects’ reproduction cycle.  

Conquer is not labeled to be used on peach trees.  You can use a product that contains permethrin but it must be labeled for use on non bearing edible vegetation such as Tengard SFR. Unfortunately once the beetles have already infested the bark of a peach tree there are not any viable treatment options. In cases of infestation the general recommendation is to simply protect the surrounding trees with preventative sprays with a product labeled for such a use.

Conquer is labeled for all species of crickets. You will mix 2 fl oz per gallon of water per 1,000 sq ft. Please the label below for more detailed information.

Conquer Product Label

Conquer is not labeled to be used for mosquitoes outdoors. Talstar is our most popular selling product for mosquito control.  It is a liquid concentrate that you mix with water and apply using a sprayer.  You will need about 1 oz of product for every 1,000 sq ft of space you need to treat. The key is to apply it to all shrubs, trees, and other foliage around the house or patio where you are trying to provide relief.  It should be directed not only on top of the leaves and plants, but on the underside of the leaves as well which is where the mosquitoes hang out.  Talstar should be applied every 30 days for optimum control.
