There is disclosed a method for fighting infestations of acari or noxious insects including ants, more particularly "fire-ants", by treating the insect, its habitat, or its food with a hydroquinone diether having at least one acetylenic and halogen-substituted chain and selected from 1-[(5-chloro-pent-4-inyl)-oxy]-4-phenoxybenzene of formula ##STR1## and 1,4-di-(5-chloro-4-pentinyloxy)-benzene of formula ##STR2## The disclosure comprises a method for fighting ants using the diether of formula (I) either as such or as an active ingredient of suitable formulations or poisoned baits.

An aqueous formulation for the control of social insects, especially wasps, and a method for its use. The formulation contains insect attracting ingredients and a toxicant in water. The toxicant is a hemisalt preparation of a perfluoroalkane sulfonic acid which is partially neutralized to a pH of between 2.8 and 6.5.
A method of treating a population of social insects includes applying topically to the insect a composition comprising a carrier and an active ingredient. The composition provides a coating that adheres to the insect and is groomable and ingestible by other insects to distribute the active ingredient within the population. In accordance with a preferred embodiment, the composition includes sulfluramid as an active ingredient and an air dryable resin as a carrier. A trap for collection of insects controls temperature within the trap to promote recruitment and also drive the insects to a collection area where they may be treated.
A process for preparing an aromatic propargyl ether, preferably bispropargyl ether, from phenolic compounds comprising vigorously stirring a propargyl halide, preferably propargyl chloride, with a phenolic compound, such as bisphenol A, in an aqueous sodium hydroxide solution at a temperature of from about 0.degree. C. to about 100.degree. C., in the presence of a phase transfer catalyst such as tetrabutylammonium bromide. The mixture is then filtered to recover a solid product. That product is washed with water and propanol. This process provides a product having greater than 98% purity in yields ranging from 85 to 97% of theoretical.
A method for preparing and a product made thereby for a bait insecticide composition that is toxic toward fire ants (Solenopsis saevissima v. richterii). Such a composition is comprised of an attractant agent (concord grape extract) mixed with a toxicant (organophosphorous compound) and an enhancing agent (salt). This present invention has the ability to control fire ants while remaining environmentally safe by being inert with regard to most other ants and nearly all other types of insects, rodents and mammals.
A composition is disclosed from controlling an insect population including an insect food stuff and an insecticidally effective amount of at least one Gram negative bacteria, viable, dead or alive, and/or an extract thereof, where the composition is applied to an area accessible to the insects and results in insect death. The compositions are ideally suited for the control of fire ants, cockroaches, carpenter ants and termites. For fire ant and cockroach control, the food stuff is a carbohydrate rich material, while for carpenter ant and termite control, the food stuff is a cellulosic rich material. The composition is applied to the area as a single treatment or as a periodic treatment in an amount have from about 5.times.10.sup.9 to about 1.times.10.sup.13 bacteria or extracts from that number of bacteria.
