Pesticide Permanone 30-30

Asked June 5, 2018, 4:42 PM EDT

What insects, other than 'skeeters, does this kill. We do not want to harm any other insects. We have many (!) mantices, bees butterflies, etc. Also concerned about toxicity to birds, lizards, etc. which will ingest the dying insects. Are there products specific to mosquitoes? Thank you,

Please contact the National Pesticide Information Center for your question on Permanone 30-30. They specialize in pesticide safety questions.
In Maryland, insecticides registered for use to control adult mosquitoes may include the following active chemical ingredients: naled, piperonyl butoxide, tau-fluvalinate, bifenthrin, and permethrin. (Source: Maryland Department of Agriculture) The latter three of these are in a class of chemicals called pyrethroids. They are broad-spectrum pesticides, meaning they do not target just one type of insect and may kill or negatively affect bees and other beneficial insects. They are also toxic to fish and other aquatic organisms and should not be applied near a water.

Also look at the information on our website about mosquito control:

I understand there are biological agents which specifically target adult and/or larval stages of mosquitoes. Are they avalible to Md. residents in lieu of pesticides that are toxic to desirable insects. Does your dept. do this? If not, can you tell me who does, please? Thanks again.

Control of mosquitoes, as noted in the link above, is related to habitat management such as getting rid of standing water wherever you can, and where you can't, you can use the bio-pesticide Bt to control the larval stage, which is harmless to non-target life forms.

It is available to homeowners in the form of Mosquito Dunks (look like small brown, granular donuts) and granules. The active ingredient is Bacillus thuringiensis israeliensis (Bti), a bacterium that produces proteins that are toxic for certain fly larvae. You put them in the standing water and they last for about 30 days. Read labels for use.

As the link above covers, doing a yard scan and dumping accumulated water a couple of times a week is important. Be sure to check things like

  • Toys
  • Swings
  • Buckets and containers
  • Wheelbarrows
  • Bird baths
  • Flower pots
  • Poorly draining gutters
  • Sagging tarps
  • Plastic pools
  • Tree holes
  • Cesspool or septic tank
  • Untreated and non-functioning swimming pools
  • Tires
  • Cisterns or rain barrels
  • Low ditches or parts of the yard
  • Stagnant ponds

Dunks are o.k. for standing, relatively clear (of stands of grass, etc.). Are there aerosol versions? Any similar product which targets the adult skeeters?

There is no aerosol version of Bt (Mosquito Dunks). For controlling adult mosquitoes, wear personal repellants containing DEET, picaridin, Icaridin, or oil of lemon eucalyptus. Wear long pants and long-sleeved shirts. Use a fan in outdoor seating areas. For additional options, look at the information on our website about mosquito control:
