Talstar P is labeled for almost every insect you could have a problem with (including fleas, ticks and mosquitos) and you can use it outside the home as well as inside, it is odorless and very safe for use around children and pets. A hand pump sprayer or backpack sprayer would be the preferred, but the method of application will not determine the results of the product.
An insecticide like Talstar P would be a great option for you for all of these pests, along with many others. It is recommended to also use an insect growth regulator (IGR) like Archer IGR for fleas and ticks to stop them from reproducing. Both of these products can be applied with a hand pump sprayer. You may also want to look over our Pest Prevention Guide for more information.
Talstar P Professional Insecticide can be mixed with insect growth regulators such as Precor IGR. Be aware though that Precor is only labeled for use indoors but Talstar cannot be used as a broadcast across surfaces inside the home such as carpets (it is only for cracks and crevices) so if you are treating for fleas it is not the best option as an insecticide. Instead you should use something like Conquer or Onslaught.

Talstar P would be your best general insecticide for your yard. It is labeled for just about any insect you could have a problem with including ants, roaches, beetles, mosquitoes, and many others. Talstar P can be used in a hose end sprayer but can be a little thick so may need a touch of water added to thin it a bit.
If you are looking to get rid of the weeds and grass so you can reseed you should use a glyphosate product such as Glyphosel Pro. This is a non-selective herbicide that will kill the weeds and anything other foliage it is sprayed on. You can reseed after 14 days. Do not directly spray the trees or allow drift to get on the trees to avoid damage.
